Answer only if you are doing A TO D

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 6.6 kg, it is pushed 3.3 m vertically upward, the coefficient of friction is 0.35, and the angle is 30.0⁰°, determine the following.
(a) the work done (in J) on the box by F
449.3
x
A force diagram will help you determine the magnitude of the force F acting on the box. Then you can determine the work done on the box by this force.
(b) the work done (in J) on the box by the force of gravity
-213.44
(c) the work done (in J) on the box by the normal force
0
✓ J
(d) the increase in gravitational potential energy (in J) of the system of the box and earth as the box moves up the wall
