2/13 A ball is thrown vertically upward with an initial speed of 80 ft/sec from the base A of a 50-ft cliff. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the impact velocity UB. Neglect air resistance and the small horizontal motion of the ball. 50 Uo Problem 2/13
