A ball is thrown vertically upward with an initial speed of 73 ft/sec from the base A of a cliff with H = 39 ft. 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 magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball.
