Thanks for clarifying!

I see! I didn't read the question carefully sorry. Velocity at maximum height is 0, so v=0. And the Initial velocity on the Moon and the Earth is the same. Simultaneous equation? v^2=u^2+2as u^2=-2as, u^2 for Earth and Moon is the same. -2as(Earth) = -2as(Moon) s(Moon)/s(Earth) = 19.62/3.27...

I tried using v^2 = u^2 +2as. Initial velocity = 0, so u^2 = 0 v^2 = 2as when a = 9.81, s= v^2/19.62 v^2 = 2as when a = 1.635, s=v^2/3.27 What value of v can I use? Or am I using the wrong formula?

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...
