A man pushes an 800 n crate a distance of 500 m upward, Ask an Expert

Academics

A man pushes an 80.0 N crate a distance of 5.00 m upward along a frictionless slope that makes an angle of 30o with the horizontal. The force that he exerts is parallel to the slope. If the speed of the crate increases at a rate of 1.50 m/s2, how much work is done by the man?
