• ID Code: C7-21
• Purpose: Illustrate conservation of momentum and conservation of energy.
• Description: A pool ball, suspended as a pendulum of length L, is released from an angle a and collides with an identical pool ball initially at rest. The second pool ball then immediately projects horizontally off the edge of the lecture table of height H. The range R of the projected ball is given by R = 2 SQRT [ LH (1 - cos a)]
