A simple pendulum consists of a small ball of mass m = 200g swinging on a massless, inextensible string of length R = 7m. At time t = 0 the pendulum is released from the horizontal position, as shown below. A short time later, the pendulum reaches the bottom of its swing and encounters a nail sticking out of the page a distance L = 6m below the pivot point. The pendulum begins to wrap around the nail, and at time t = t top it is at the top of its first rotation. t = 0 R m L nail t = t top
Ball, because it has mass and is moving.
