Physics

3. (I) How much work did the movers do (horizontally) pushing a 150 kg crate 12.3 m across a rough floor without acceleration, if the effective coefficient of friction was 0.70? Answer: 1.3 x 10⁴ J.

5. (I) How high will a 0.325 kg rock go if thrown straight up by someone who does 115 J of work on it? Neglect air resistance.

9 (II) Eight Books, each 4.6 cm thick with mass 1.8 kg lie flat on a table. How much work is required to stack them one on top of another?

10. (II) A 280 kg piano slides 4.3 m down a 30 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 0.40. 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, and (e) the net work done on the piano.
