On the Moon, the acceleration due to gravity is 1.6 m/s2 and there is no atmospheric drag.  During Apollo 14, Alan Shepherd hit a golf ball on the Moon.  If he hit the ball at an angle of 20° with an initial velocity of 35 m/s, find the total time the ball was above the ground.  Assume it landed at the same height as it was hit.
