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.
