A ball with a mass of 1.1 kg is initially at rest. It is struck by a second ball having a mass of 1.3 kg, initially moving with a velocity of 3.5 m/s toward the right along the x axis. After the collision, the 1.3 kg ball has a velocity of 2.7 m/s at an angle of 35? above the x axis in the first quadrant. Both balls move on a frictionless, horizontal surface. Do not assume that the collision between the two balls is elastic.

(a) What is the velocity (its magnitude and direction) of the 1.1 kg ball after the collision?

(b) What is the change in the total kinetic energy of the two balls as a result of the collision?

A cue ball (mass = 0.170 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick, which applies an impulse of +1.20 N · s to the ball. The ball then slides along the table and makes an elastic head-on collision with a second ball of equal mass that is initially at rest. Find the velocity of the second ball just after it is struck. ? m/s
