10. (II) A 380-kg piano slides 2.9 m down a 25° incline and is
kept from accelerating by a man who is pushing back on
it parallel to the incline (Fig. 6-36). Determine: (a) the
force exerted by the man, (b) the work done on the piano
by the man, (c) the work done on the piano by the force of
gravity, and (d) the net work done on the piano. Ignore
friction.
