    A cue ball traveling at 6.47 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision. 90 ° (correct) (b) Find the speed of each ball after the collision. cue ball     m/s target ball     m/s

    A steel ball of mass m = 1 kg and a cord of negligible mass and length L = 2 m make up a simple pendulum that can pivot without friction about the point O (see below). This pendulum is released from rest in a horizontal position and when the ball is at its lowest point it strikes a block of mass m = 1 kg sitting at rest on a shelf. Assume that the collision is perfectly elastic and...
