Halliday, Resnick & Walker — Center of Mass and Linear Momentum: Problem 35

35 Figure 9-45 shows an approximate plot of force magnitude F versus time t during the collision of a 58 g Superball with a wall. The initial velocity of the ball is 34 m/s perpendicular to the wall; the ball rebounds directly back with approximately the same speed, also perpendicular to the wall. What is Fmax, the maximum magnitude of the force on the ball from the wall during the collision?
