The velocity of a 4.5 pound object falling from a height of thirty feet can be calculated using the equation for free-fall motion: ( v = \sqrt{2gh} ), where ( v ) is the velocity, ( g ) is the acceleration due to gravity (32 ft/s(^2)), and ( h ) is the height. Substituting the values, you can calculate the velocity of the object when it reaches the ground after falling thirty feet.

How much weight does a 80 pound object falling 10 feet create?
The force a falling object exerts upon impact is dependent on the object's mass, gravity, and the distance fallen. Using the formula F = mgh, where F is the force, m is the mass, g is the acceleration due to gravity, and h is the height fallen, the force exerted by an 80-pound object falling 10 feet would be approximately 3520 pounds.
What is the net force of a 7 pound object falling 20 inches?
The net force acting on the object can be calculated using the equation F = m*a, where F is the force, m is the mass of the object, and a is the acceleration due to gravity. The mass of the object can be converted from pounds to slugs, and the acceleration due to gravity is approximately 32 ft/s^2. Plugging in the values, we can calculate the net force.
Why the air resistance decrease the acceleration on falling object?
Air resistance applies a force opposite to the direction of motion of a falling object. This force opposes the force of gravity, reducing the net force acting on the object, and hence reducing its acceleration. As the object's speed increases, the air resistance force also increases, further hindering its acceleration.
What weighs more a pound of books or a pound of feathers?
The weigh the same. A pound is a pound is a pound no matter what the object is.
How many pounds are in thirty seven ounces?
well there are 16 ounces in a pound so just do 37 times 16 and that should give u the answer

How long does it take for a 200 pound object to fall 692 feet?
If they're not falling through air, then a bean and a battleship both fall 692 feetin 6.556 seconds. The weight of the object makes no difference.If the object IS falling through air, then in order to answer the question, we need toknow the object's shape, size, and volume, plus the temperature, humidity, density,and pressure of the air, at every altitude between the ground and 692 feet.
How many feet will a 100 pound object fall in 7 seconds?
Any object near the surface of the earth, falling without air resistance and under the influence of only gravity, falls 789 feet. (rounded) Its weight makes no difference.
