Collision 1. Two balls of equal mass but different composition are dropped from the same initial height of 1 m. Ball A bounces to a height of 0.5 m. Ball B only bounces 0.01 m. What is the change in momentum during collision for (a) Ball A (b) Ball B A ping-pong ball with mass m and initial momentum < p1x, 0, 0 > collides head- on with a bowling ball with mass M = 1000m that is at rest. It is an elastic collision, and the net external force on the system is zero. 2. What is the momentum of the ping-pong ball after the collision? 3. What is the momentum of the bowling ball after the collision? A cue ball makes a glancing collision with the 8-ball. Let’s assume that they have the same mass. In reality, the cue ball has a slightly larger mass, but let’s keep things simple. The incoming cue ball has a velocity < 1.5, 0, 0 > m/s. After the collision, the cue ball’s velocity has an angle of 20 deg with respect to its original direction of motion, and the 8-ball’s velocity has an angle of 60 deg with respect to the original direction of motion of the cue ball. Treat the two billiard balls as a
