A pendulum, made of a mass m= kg tied to the end of a string of length L= m as shown in the left figure here. This position is called the "equilibrium" or "relaxed" position of the pendulum. If pulled and released, the pendulum can can swing freely from side to side.

If it is pulled up to an angle = degrees as shown in the right figure, then released, what speed does it have when it again swings through the "equilibrium" position shown in the left figure?
