A sprinter starts from rest and accelerates at a rate of 0.16 ms−2 over a distance of 50.0 meters. How fast is the athlete traveling at the end of the 50.0 meters?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Which situation will produce the greatest change of momentum

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
