A 350kg piano slides 3.7m down a 33^\circ incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (see the figure(Figure 1) ). The effective coefficient of kinetic friction is 0.32.

Part A Calculate the force exerted by the man. Express your answer using two significant figures.

Part B Calculate the work done by the man on the piano. Express your answer using two significant figures.

Part C Calculate the work done by the friction force. Express your answer using two significant figures.

Part D Calculate the work done by the force of gravity. Express your answer using two significant figures.

Part E Calculate the net work done on the piano.
