Question

A simple pendulum consists of a small ball of mass m=0.2kg swinging on a string of length 7m. The pendulum is
released from the horizontal position, as shown in Figure 1. A short time later, the pendulum reaches the bottom of its
swing and encounters a nail sticking out of the page a distance 6m below the pivot point, and the pendulum begins to
wrap around the nail. How fast is the ball moving when it is at the top of its first rotation around the nail?
