An electric motor is used pull a 20 kg block up along an incline of angle 12.0 degrees. The coefficient of kinetic friction between the block and the incline is 0.350 and the block is pulled at a constant velocity along a distance of 800 meters during a time of 400 seconds. (a) Draw a free body diagram for the block. (b) Calculate the energy transfer (work) due to each of the forces. (c) What is the power of the electric motor during the time when the block is being pulled?

Question
An electric motor is used pull a 20 kg block up along an incline of angle 12.0
degrees. The coefficient of kinetic friction between the block and the incline is
0.350 and the block is pulled at a constant velocity along a distance of 800
meters during a time of 400 seconds. (a) Draw a free body diagram for the
block. (b) Calculate the energy transfer (work) due to each of the forces. (c)
What is the power of the electric motor during the time when the block is being
pulled?
