Question

A dropped wad of clay having a mass of 0.5 kg was traveling at 10 m/s just before it hit the ground and stopped.

a) What was the momentum of the wad just before it hit.

(Note: Take UP to be in the positive direction and DOWN to be in the negative direction.)

(b) What is the change in momentum of the wad?

(c) What impulse is imparted to the wad by the ground?

(d) A rubber ball having the same mass as the clay is dropped. It too has a speed of 10 m/s just before it hits the ground. The ball bounces and leaves the ground with a speed of 5 m/s.

What is the momentum of the ball just as it leaves the ground?

(e) What impulse is imparted to the ball by the ground?

(f) If the time of contact between the ball and the ground is 0.04 s, what is the magnitude of the average force that the ground exerts onthe ball during the collision?
