A child, m = 25.0 kg, swings from a rope, L = 8.57 m, which hangs above water, d = 1.1 m, when vertical. The child is h = 7.1 m above the water when she begins to swing. Part A: Write an expression for the velocity v of the student at the bottom of the swing. Part B: Assume the child lets go at the bottom of the swing. How long does she take to reach the water, t in seconds?
