Rafael drops a hard rubber ball, of mass m = 310 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. - Enter an expression for the magnitude of the impulse delivered to the ball by the ground, in terms of Fmax and the time intervals Δt1 and Δt2.  (I=?) -  For the time intervals Δt1 = 2.5 ms and Δt2 = 5.5 ms, what is the magnitude of the maximum force between the ground and the ball, in newtons?  (Fmax = ?)

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
