Finding work with displacement and weight.

[Bluepie97]

Homework Statement

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.

Homework Equations

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

 

[Bluepie97]

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

Yup...its correct...!
