This shows the
forces acting on a
box which is being
pushed up a slope.
Calculate the work
done by each force
if the box moves
0.50m up the slope

I wonder why this q be posted here...But this is not that difficult, all you need is to find out magnitude of each force along with the direction of the box moving. That is, dividing the forces to orthogonal ones, which are horizontal to the slope and vertical the other. Cross product may help but I think it's no neccessity.

The work exerted on the box is the magnitude of the "horizontal" force times the moving distance 0.50 m
