1. The problem statement, all variables and given/known data A person can jump a maximum horizontal distance (by using a 45 ◦ projectile angle) of 4 m on Earth. The acceleration of gravity is 9.8 m/s 2 . What would be his maximum range on the Moon, where the free-fall acceleration is g 6 ? Answer in units of m. 2. Relevant equations Kinematics equations 3. The attempt at a solution All I can think to do is set kinematics equations for the x and y axis equal to each other by another variable, such as time. This is as far as I can figure out with this problem.
