What is the initial velocity of the ball

Reference no: EM13518356

A 4.0 kg ball is on the end of a 1.6 m rope which is fixed at O. The ball is held at point A, with the rope horizontal, and is given an initial downward velocity. The ball moves until it arrives at point B, with the rope barely under tension (i.e. tension force at point B is zero). What is the initial velocity of the ball, at point A, in m/s?
