Trying to do Ohanian and Markert page 301 q71: Suppose that a projectile is fired horizontally from the surface of the Moon with an initial speed of 2.0 km/s. what height will this projectile reach? What will be its speed when it reaches maximum height. The answer is not that velocity equals 0 as I would expect but 817 m/s. can anyone explain how to do it? Thanks
