Aclay ball with a mass of .045 kg is attached to a long string to make a pendulum. the ball is pulled back so that the string is horizontal to the ground, and is then released. at the bottom of the ball’s path is another clay ball that has a mass of .075 kg and is at rest. the two balls collide elastically so that they follow the path of the first ball beyond the point of collision.
(a) what must the speed of the first ball be just before the collision so that the combined balls rise to a height of .08 m above the point of collision?
(b) how high must the first ball be raised for it to have this speed at the bottom of its path?
