A block of mass 1.00 kg
sits on an inclined plane as shown. (Figure 1)A force of magnitude 90.0 N
is pulling the block up the incline. The coefficient of kinetic friction between the plane and the block is 0.500. The inclined plane makes an angle 50.0 degrees with the horizontal.
What is the total work Wfric done on the block by the force of friction as the block moves a distance 6.00 m up the incline?
