Finding the phase angle of a pendulum swinging.

  1. Dec 15, 2009 #1
    1. The problem statement, all variables and given/known data

    The question reads:

    Two identical pendulums have the same amplitude and the same length (20cm) At time t = 0, one pendulum reaches the end of its swing at x = +6 cm. At the same time the second pendulum has velocity v = -27 cm/s and sits on opposite ends of the equilibrium position. Find the phase angle of the second pendulum.


    2. Relevant equations



    3. The attempt at a solution

    Ive tried several things but im hung up on finding the position of the 2nd pendulum at time 0.
