Finding the phase angle of a pendulum swinging.

[meeklobraca]

Homework Statement

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.

Homework Equations

The Attempt at a Solution

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