A 350kg piano slides 3.8m down a 29 degree incline and is kept from accelerating by a man who is pushing back on it parallel to the incline . The effective coefficient of kinetic friction is 0.35.
Part A Calculate the force exerted by the man.
Part B Calculate the work done by the man on the piano.
Part C Calculate the work done by the friction force.
Part D Calculate the work done by the force of gravity.
Part E Calculate the net work done on the piano.
