Question

A 170 g ball is dropped from a height of 2.4 m. It bounces on a hard floor and rebounds to a height of 1.7 m. The graph shows the impulse received by the ball from the floor. calculate the maximum force exerted on the ball by the floor. t=4
Force = change in momentum/ change in time
in other words the max force is the max slope of the impulse versus time curve
The graph is a force vs time graph with no numbers... how would i find the max force from that?
