4. With your height difference from number 3, you're ready to use the conservation of energy. Since the energy at the bottom of the swing must equal the energy at the top of the swing, use that fact to find the velocity of the pendulum in terms of the length of the pendulum, the acceleration of gravity g, angle 8, and the masses.
