Name: In the figure, a 4.0-kg ball is on the end of a 1.6 m rope that 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 through three-quarters of a circle with no friction and arrives at B, with the rope tension=76.5 N. The initial velocity of the ball in m/s, at point A, is closest to
