Problem: A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0-m-high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground. Ignore air resistance on the ball.(a) At what angle above the horizontal should the ball be thrown so that the runner will catch it just before it hits the ground?(b) How far does she run before she catches the ball?
