Rafael drops a hard rubber ball of mass m=285g from rest at a height of h1=3.22m. It strikes the pavement and bounces back to a height h2=1.73m. 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. If the two time intervals are Δt1=1.82ms and Δt2=5.29ms, then what is the magnitude, in newtons, of the maximum force between the ground and the ball?
