A 330kg piano slides 3.6m down a 28degrees incline and is kept from accelerating by a man is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40.
Calculate:
a. the force exerted by the man
b. the work done by the man on the piano
c. the work done by the friction force
d/ the work done by the force of gravity
e. the net work done on the piano
any help wuld be great
thanks
