A horizontal force of magnitude F = 110 N is used to push a box of mass m = 6 kg from rest a distance d = 16 m up a frictionless incline with a slope q = 28°.
a) How much work is done by the force on the box?
b) How much work is done on the box by the gravitational force during this same displacement?
c) How much work is done by the normal force of the slope on the box during this displacement?
d) How fast is the box moving after this displacement?

Hi Lyla,

Posting homework questions online for free answers is against the course policy. Please do not do this because it is cheating. If you need help contact your TA or come to my office hours.
