(a)  A hiker throws a ball at 21.0 above the horizon from a 21.0 m high hill. The hiker is 1.750 m tall. The magnitudes of the horizontal and vertical velocities are 14.004 m/s and 5.376 m/s, respectively. Find the distance from the base of the hill and the point where the ball hits the ground below the hill.
