Homework Help: Projectile Problem

  1. Sep 19, 2010 #1
    1. The problem statement, all variables and given/known data
    you hit a golf ball 180m on the moon, but on earth you only hit it 30m. Assuming that everything is the same (swing, launch angle, etc..) find the gravity of the moon.


    2. Relevant equations
    a = -g (on earth)
    Xe = 30m
    Xm = 180m


    3. The attempt at a solution

    I really don't know where to tackle this problem from. I need assistance.

    It is projectile motion, the same magnitude and angle of initial velocity, only the value of g is different. How long is the projectile above ground? What is the horizontal distance the projectile travels during this time?
