You push a heavy crate out of a carpeted room and down a hallway with a waxed linoleum floor. while pushing the crate 2.5 m out of the room you exert a force of 385 n; while pushing it 10 m down the hallway you exert a force of 130 n. to slow it down you exert a force of 350 n through a distance of 2.0 m, opposite to the motion. how much work do you do in all?
