A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is 1/6 as large.
How does the maximum altitude of the projectile on the Moon compare with that of the projectile on the Earth?
