100 x 3 = 300 joules
The work done is stored as potential energy of the box P=Mgh F=Ma (a=g) F=Mg h=5m Therefore the work done is 20*5 = 100 joules -----------------------------------------------------------------------------------------------------
Work = force x displacementW = Fd W = 100N x 3m W = 300J 300 joules of work is done on the box.
A joule is a neuton metre. i.e. 10*5 = 50 joules are required.

If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
If a 100 N box is lifted 3 meters off the ground, the answer is 300 joules.
980 w=m x g x d
100 x 3 = 300 joules
