Two piano movers are bringing a piano into a home. One mover pushes to the right with a force of 310 N, while the other pulls to the right as well, but with a force of 270 N. The force of friction acts to the left, with a magnitude of 190 N. The piano weighs 2500 N. What is the net force on the piano?

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
