Homework Help: Pendulum physics problem

  1. Apr 21, 2004 #1
    Two pendulums, both of length l = 1.0m, are initially situated as shown in the below figure. The left bob has a mas m1 = 1.0kg and is held a distance d = 0.50m above the center of the right bob, of mass m2 = 2.0kg. The left pendulum is released and strikes the other. Assume that the collsion is completely inelastic, and neglect the mass of the string and frictional effects. How high does the pendulum system rise after the collision?

    1. Use conservation of mechanical energy on the swinging pendulum to determine its impact velocity.
    2. Use impact analysis to determine the system's velocity after impact.
    3. Use conservation of energy of the system to determine the max. displacement.
