A microwave oven of mass 12.5kg is pushed a distance 8.00m up the sloping surface of a loading ramp inclined at an angle of 36.2? above the horizontal, by a constant force F? with a magnitude 170N and acting parallel to the ramp. The coefficient of kinetic friction between the oven and the ramp is 0.290.
a) What is the work done on the oven by the force
b) What is the work done on the oven by the friction force?
c) Compute the increase in potential energy for the oven.
d) Use your answers to parts (A), (B), and (C) to calculate the increase in the oven's kinetic energy.
