Question 26.)

Lets go ahead and assume that there is a 40 kg object is pushed upwards that will be at a constant velocity for 8 m along a 30° inclined plane by the horizontal force F. The coefficient of kinetic friction between the box and the surface will be 0.4. Please show the work for the following four forces below:

a. Applied force

b. Frictional force

c. Gravitational force

d. Net force

Answer #1

The object is moving with constant velocity, hence, no change in kinetic energy. Thus, by work energy theorem the work done by net external forces on the object is zero.
