## Homework Statement

A golf ball of mass 41.8 g is dropped from a height h = 1.41 m onto a hard floor and bounces back to exactly that same height. What is the average force (in N) on the ball during the 0.012 s that it was in contact with the floor?

## Homework Equations

Impulse = Ft

Impulse = m(Vf - Vi)

## The Attempt at a Solution

I am not quite sure how to proceed with this problem, becuase I am completely clueless as to how I should go about calculating the change in velocity, becuase if the ball returns to the same height, (no friction of air resistance) then arent the Vi and Vf both = 0?
