A child swing suspended from a tree branch has an effective length of 2.5 m. A maximum angular displacement of the rope from vertical position is 14 degrees. A total mass of the child and swing is 25 kg. Assuming that the swing can be treated as a simple pendulum find the speed of the child at the equilibrium position.
