A child of mass 40kg jumps off a wall and hits the ground at 4m/s he bends his knees and stops in 1s calculate the force required to slow him down how would this force be different if he didn't bend his knees and stopped in 0.1s
Answered by Steve
his acceleration is 4m/s^2

F = ma

1/10 the time means 10 times the acceleration.
