A 5.0kg box slides 8.0m down a ramp, inclined at 40degrees from the horizontal. If the box slides at constant velocity, the work done by gravity is?

Question

I used W=F*deltaX*costheta
=(mg)*(deltaX)*(costheta)
=(5.0)(9.8)*(8.0)* (cos50)

Which I got 252 J. Is this correct?

Answer 1

you are correct
