Rafael drops a hard rubber ball, of mass m = 130 g, onto the pavement. He drops it from a height h1 = 2.9 m, and it bounces back to a height h2 = 1.65 m. While the ball is in contact with the ground, the ground exerts a non-constant force on the ball as shown in the figure. During the time interval Δt1 the force rises linearly to Fmax, and during the time interval Δt2 the force returns linearly to zero as the ball leaves the ground. Refer to the figure. a. Enter an epression for the magnitude of the impulse delivered to the ball by the ground, in terms of Fmax and the time intervals deltat1 and deltat2. b. For the time intervals deltat1 = 3.5 ms and deltat2 = 6.5 ms, what is the magnitude of the maximum force between thr ground and the ball, in newtons?
