How do you calculate the impact force from the depth of impact?

In: Mechanics, Kinematics [Edit categories]

Answer:

v_f ² = v_i ² + 2ad

v_f is the speed after collision in your case it's 0. v_i is initial speed, a is constant acceleration (in your case it's negative), and d is distance traveled with the acceleration a. Thus we have.

a =v_i ²/2d

So the force is

F = ma = mv_i ²/2d
