When you push a shopping cart the friction that is opposing the motion is called?
When you push a shopping cart, the friction that opposes the motion is called static friction if the cart is stationary or kinetic friction if it's already in motion. Static friction acts to prevent the cart from moving, while kinetic friction acts against the motion once it starts rolling. Both types of friction arise from the interactions between the cart's wheels and the surface it moves on.
How many miles per hour over the speed limit is considered a criminal offense?
The speed at which exceeding the limit becomes a criminal offense can vary by jurisdiction. In many places, driving more than 15 to 20 miles per hour over the speed limit may result in a misdemeanor or criminal charge, especially if it endangers others. However, specific laws can differ, so it's important to consult local traffic regulations for precise information.
What energy is transferred as a golf club does work on a golf ball?
When a golf club strikes a golf ball, kinetic energy from the club is transferred to the ball. This energy transfer propels the ball forward, converting the club's motion into the ball's motion. Additionally, some energy may be converted into sound and heat due to friction during the impact. Overall, the primary energy transferred is kinetic energy.
Will you die from a 30 foot free fall?
A 30-foot free fall can be extremely dangerous and potentially fatal, depending on various factors such as the surface you land on, your body position during the fall, and overall health. Injuries from such a fall can range from serious fractures to life-threatening trauma. While some individuals may survive a 30-foot fall, the risk of severe injury or death is significant. Always prioritize safety and avoid risky situations involving heights.
HOW DO YOU CHANGE THE DASH FROM KPH TO MPH ON TRX350FE?
To change the dash from kilometers per hour (KPH) to miles per hour (MPH) on a TRX350FE, start by turning on the ignition without starting the engine. Then, locate the trip meter button on the display and press and hold it until the display changes. Keep holding the button until the unit switches from KPH to MPH. Release the button to save the setting.
What happens when potential energy and kinetic energy of a ball as it rolls down a hill?
As the ball rolls down a hill, its potential energy (due to its position at the top of the hill) is gradually converted into kinetic energy (due to its motion). This conversion is a result of the force of gravity acting on the ball as it moves downhill. The ball's speed increases as it descends, and at the bottom of the hill, most of its initial potential energy is transformed into kinetic energy. This process follows the principle of conservation of energy, where the total mechanical energy (potential energy + kinetic energy) of the ball remains constant throughout its motion.
The speed of 700 watts in mph depends on various factors such as the weight of the object/vehicle using the power. It is not a direct conversion as mph is a measure of speed, while watts is a measure of power. If you are referring to a human on a bicycle, they might be able to maintain around 20 mph with an output of 700 watts.
Work done is scalar or vector?
Oh, dude, work done is actually a scalar quantity. It's like measuring how much energy is transferred when a force acts on an object, but it doesn't care about direction or anything fancy like that. So yeah, work done is just a simple scalar, no need for vector drama here.
How long will it take to travel a mile at 1000 mph?
Roughly 10750 years. (:
It depends on how fast you are traveling. At the speed of light, it would take one year to travel a distance equal to one light year. The speed of light is about 186,282 miles per second. This works out to over 670 million miles per hour and about 5.87 trillion miles per year. So a distance of one light year is equal to a distance of about 5.87 trillion miles. At the speed of an interplanetary space probe traveling at a velocity of 40,000 miles per hour, it would take 16,765 years to travel one light year. The nearest star besides our sun, Proxima Centauri, is about 4.3 light years away. At a speed of 40,000 miles per hour, the velocity of our interplanetary space probe, it would take a little over 73,000 years to reach Proxima Centauri.
Oh, honey, 32 kilometers per hour is about 19.88 miles per hour. So, if you're cruising along at that speed, you're moving faster than a sloth but slower than a cheetah. Just keep an eye out for speed bumps, darling.
How fast does a bullet travel?
The speed of a bullet can vary depending on the type of weapon and ammunition used. However, on average, bullets fired from handguns typically travel at speeds ranging from 800 feet per second (fps) to 1600 fps, while bullets fired from rifles can travel at speeds exceeding 3000 fps.
How fast can a 11 year old run in mph?
im 11 y/o and i can run about 16mph, and my older brother can run 19-21mph but hes 19 y/o
To convert frequency to speed, we need more information. Frequency (27 MHz) alone does not directly translate to speed in miles per hour (mph). Frequency typically measures the number of cycles per second, while speed is a measure of distance traveled over time. To calculate speed in mph, we would need additional details such as the wavelength or the type of wave (e.g., sound wave, radio wave) to determine the relationship between frequency and speed.
How many minutes does it take to drive 58 miles away at 75 mph?
To calculate the time it takes to drive 58 miles at 75 mph, you can use the formula: time = distance / speed. In this case, time = 58 miles / 75 mph = 0.773 hours. Since there are 60 minutes in an hour, you would multiply 0.773 hours by 60 minutes to get the answer: approximately 46.4 minutes.
You should allow at least 4 seconds of following distance when driving a 30-foot vehicle at 55 mph. This provides enough time to react to any sudden changes in traffic ahead and helps prevent rear-end collisions.
How do you convert 264 yards per second to miles per hour?
To convert yards per second to miles per hour, you can use the conversion factor: 1 mile = 1,760 yards and 1 hour = 3,600 seconds.
So, to convert 264 yards per second to miles per hour: 264 yards/second * 1 mile/1,760 yards * 3,600 seconds/1 hour ≈ 169.09 miles per hour.
The total energy of an object is called?
Kinetic Energy is equal to 1/2mv^2.
Potential Energy is equal to mgh.
To get the total potential and kinetic energy of an object, you do the following:
1/2mv^2+mgh = Total Energy.
m represents mass in kg
v represents velocity in m/s
g represents gravity, a constant of 9.8 m/s^2
h represents height from ground in m
What are some advantages and disadvantages of specialization?
Specialization allows a person to become skilled and efficient at a specific task; he or she will then be able to produce much more of a good (or service) at a higher quality by himself than many other unskilled laborers attempting to do the same thing. This allows others to specialize in another task.
For example, one person could specialize in making a wheel, another in making the frame of a car, another the engine, etc.. By specialization they can efficiently do their individual tasks and together produce more cars than if they each attempted to create every part of the car by themselves.
Can an object have kinetic energy but no momentum?
Well, honey, technically speaking, yes, an object can have kinetic energy without momentum. See, momentum depends on both an object's mass and velocity, while kinetic energy only cares about velocity. So, if you have an object with mass but no velocity, it won't have momentum but can still have some kinetic energy.
What animal can run up to 20 mph?
The animal that can run up to 20 mph is the American Bison (Bison bison). Bison are known for their impressive speed and agility despite their large size. They can reach speeds of up to 35 mph in short bursts when necessary. This ability to run at high speeds is crucial for their survival in the wild.
How many feet can a person run in a second?
The average person can run at a speed of about 10-15 feet per second, depending on their fitness level and stride length. Elite sprinters can reach speeds of over 25 feet per second. It's important to note that individual differences in running ability can significantly impact this measurement.
What are examples of low friction materials?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
If you can run 15 mph how fast would that equate into a 40 yard dash time?
To convert speed (in this case, 15 mph) to time taken to run a specific distance (40 yards), you need to first convert the speed to yards per second. Since 1 mile is approximately 1760 yards and 1 hour is 3600 seconds, 15 mph is equivalent to 22 yards per second. Therefore, to cover 40 yards at a speed of 15 mph (22 yards per second), it would take approximately 1.82 seconds (40 yards divided by 22 yards per second).
