question at position 2 a clay ball is moving with a velocity of 5 m/s towards the ground just before it strikes the ground, and then strikes the ground coming to a stop within a time of 0.5 s. a rubber ball is moving with a velocity of 5 m/s towards the ground when it then hits the ground and rebounds with a final velocity of 5 m/s towards the sky over a collision time of 0.2 s. if the clay ball and rubber ball have the same mass, determine the ratio of the force of the ground on the rubber ball to the force of the ground on the clay ball (ratio
