A 340kg piano slides 3.5m down a 29degree 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 0.30.
Q1-Calculate the force exerted by the man.
Q2-Calculate the work done by the man on the piano
Q3-Calculate the work done by the friction force
Q4-Calculate the work done by the force of gravity
Q5-Calculate the net work done on the piano.
