Trajectories on the Moon

An astronaut on the moon hits a golf ball horizontally from the top of a cliff 750 m high. The initial speed of the ball is $v_0 = 120$ m/sec. Assume that the acceleration due to gravity on the moon is $a_m = g/6 = 5/3 = 1.67$ m/sec$^2$.

a) How long does it take the ball to reach the ground (neglect the curvature of the moon)?

b) How far from the base of the cliff does the ball strike?

c) How fast is the ball going when it hits the ground?
