63. Two billiard balls of identical mass move toward each other. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are 30 cm/s and -20 cm/s, assume friction and rotation are unimportant What are the velocities of the balls after the collision? Find the final velocity of the two balls if the ball initial velocity of -20 cm/s has a mass equal to one half of the ball with initial velocity 30 cm/s

HW 5.5. The drawing shows a top-view of a collision between two balls. Ball A has a mass of 0.03 kg and is moving along the positive c-axis at 5.5 m/s. It makes a collision with ball B, which has a mass of 0.05 kg and is initially at rest. The collision is not head-on. After the collision, the two balls fly apart with the angles shown in the drawing below. + 5.5 m/s At rest a) What are the...
