A 10 kg box on wheels is moving with a velocity of 2.0 m/s. A force is applied to the box over a distance of 1.25m, after which the velocity has been reduced to 0 m/s. Answer the questions below. What was the average force (F1) applied to the box to bring it to a stop?
During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball?

i would appreciate a quick answer 1. The graph shows the velocity of a runner in a time 16 s. a. Determine the acceleration of the runner from 0-2s 8 12 t (s) b. Calculate the total distance covered by the runner from 0-16 s. c. Calculate the average velocity of the runner during these 16 s.
At the end of a race a runner decelerates from a velocity of 8.70 m/s at a rate of 2.40 m/s2. How far in meters does she travel in the next 4.10 s? (Assume the deceleration of 2.40 m/s2 is constant over the full 4.10 s.) m What is her final velocity in m/s? Evaluate the result. Does it make sense?
7. A 58 kg runner is traveling at a velocity of 5 m/s. What is her momentum (in Ns)?
During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball? Please how do you get 20/32x0.06
