A force of constant magnitude pushes a box up a vertical
surface, as shown in the figure.
The box moves at a constant speed. If the mass of the box
is 4.0 kg, and it is
pushed 2.2 m vertically upward, the coefficient of
friction is 0.35, and the angle θ is 37°.
What is the work done by the force, F? Use g = 10
m/s2.
