Astronaut Alan Shepherd brought a golf-club and two golf-balls to the Moon on the Apollo XIV mission. His second swing connected well with the ball, and its first bounce occurred 240 m from where he hit it. Assuming the surface gravity of the Moon is 1.62 m/s? and that he struck the ball with an angle 45° from the horizontal, calculate: a. The initial speed of the ball immediately after it was struck by his golf club. b. The time of flight of the golf ball before its first bounce.
