To find the velocity attained by the rocket, we can use the equation: velocity = initial velocity + (acceleration x time) First, calculate the acceleration using Newton's second law: acceleration = force / mass = 5 x 10^5 N / 2 x 10^4 kg = 25 m/s^2 Next, plug the acceleration and time (20 seconds) into the formula to find the final velocity: velocity = 0 + (25 m/s^2 x 20 s) = 500 m/s.

A change in momentum or impulse can be found by the product of mass and the change in velocity. If a force of 20 N is applied for a 2 seconds on an object. What is the impulse given to the object A) 0?
The impulse given to the object is 40 Ns (Newton-seconds). This is calculated by multiplying the force of 20 N by the time of 2 seconds. Impulse is the change in momentum experienced by an object, and it is equal to the force applied multiplied by the time over which the force is applied.
If a 500N net force is applied to a 38 kg cart for 4 seconds what is the cart's final velocity?
The final velocity of the cart can be calculated using the formula: final velocity = initial velocity + (net force/mass) * time. Assuming the initial velocity is 0 m/s, the final velocity would be: 0 + (500N / 38kg) * 4s = 52.63 m/s.
What is the velocity between 0 and 5 seconds?
To find the velocity between 0 and 5 seconds, you would need to know the position or displacement of the object at those specific times. Velocity is the rate of change of position, so without that information, the velocity between 0 and 5 seconds cannot be determined.
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 5 seconds?
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
A piece of metal has attained a velocity of 107.8 meters per second after falling for ten seconds what is its initial velocity?
the answer is 24-9 m/sec. yuor welcome
If a ball that is freely falling has attained a velocity of 19.6 meters per second after 2 seconds. What is its velocity five seconds later?
A freely falling Ball has the acceleration of 9.8 m/s/s so after 5 seconds its velocity will be: t=5s a=9.8m/s/s v=5s * 9.8m/s/s =49 m/s
What velocity does the student have after five seconds?
Velocity increases after 5 seconds

How do you get the velocity?
Velocity is derived by dividing displacement with time in seconds
If a 500N net force is applied to a 38 kg cart for 4 seconds what is the cart's final velocity?
The final velocity of the cart can be calculated using the formula: final velocity = initial velocity + (net force/mass) * time. Assuming the initial velocity is 0 m/s, the final velocity would be: 0 + (500N / 38kg) * 4s = 52.63 m/s.
What is the velocity of the object between 20 and 40 seconds?
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
What is the duration of WWE Velocity?
The duration of WWE Velocity is 2760.0 seconds.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
What is the velocity between 0 and 5 seconds?
To find the velocity between 0 and 5 seconds, you would need to know the position or displacement of the object at those specific times. Velocity is the rate of change of position, so without that information, the velocity between 0 and 5 seconds cannot be determined.
What is venus orbital velocity?
35km/seconds
What is the formula to find time in seconds from velocity and distance?
Distance divided by velocity = time
