A 50.0 kg Jalen steps off a 100.0 cm high wall. If Jalen bends his knees such that he stops his downward motion and the time during the collision is 0.250 seconds, what is the force of impact caused by the ground on Jalen?

Aball is thrown horizontally from a cliff at 8m/s .in what direction is the ball moving 2s later?

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
