The forklift exerts a 300.0 N force on the box and moves it 15.0 m into the air. How much work does the forklift do? A. 500 J B. 1.50 * 10^3 J C. 4.50 * 10^3 J D. 0.00 J

OpenStudy (michele_laino):

it is simple, the work done by forklift is equal to the Potential Energy gained by the box, so we can write: \[W = Fs = 300 \times 15 = ...\]

4500? so our solution is choice C?

OpenStudy (michele_laino):

ok!

OpenStudy (anonymous):

yay!! :D so that is correct? :O
