Homework Help: Finding work with displacement and weight.

  1. Apr 19, 2015 #1
    1. The problem statement, all variables and given/known data
    Steve lifts a 5.0kg toolbox 0.5 meters off the ground. Compare the amount of work that would be done on Earth to the amount that would be done on the moon.

    2. Relevant equations

    3. The attempt at a solution
    (no idea what i am doing)

    work = force x displacement

    x = (5/a) (.5) cos 9.8

    Hint: since the mass of moon is less than that of earth , therefore its gravity is 1/6th of the gravity at earth.

    Ok think i fixed it up a bit.
    5 x g (planet) = f
    w = f x .5

    w earth = 24.5 (units)
    w moon = 4.08 (units)
