A 0.5 kg ball is rolling down a hill going at 4 m/s. How much force is acting on the ball if it rolled for 5 m?

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
