A 17.0-lb block rests on the floor.

(a) What force does the floor exert on the block?

(b) If a rope is tied to the block and run vertically over a pulley, and the other end is attached to a free-hanging 12.0-lb weight, what is the force exerted by the floor on the 17.0-lb block?

(c) If we replace the 12.0-lb weight in part (b) with a 22.0-lb weight, what is the force exerted by the floor on the 17.0-lb block?
