It goes across.
friction
Work = force x distance = Newtons x meters = 1937 Joules.
Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.
0 since the speed is constant
891.8 newtons.

Work done = force x mass . gotcha
We must assume that the force pushes parallel to the floor.Work = (force) x (distance) = (800) x (1.5) = 1,200 newton-meters = 1,200 joules
For every action there is an equal and opposite reaction, so if you push on a crate, the crate pushes back with a normal force equal to the force exerted. Thus, expect a force of 50 N to push back at you. However, if you meant the normal force of the ground exerted on the box, then that would included the 50 N force and the weight of the crate.
Work performed = Force x displacement = 100 x 5 = 500 J (joule)
The first time you enter the room. Start by pushing the crate in the southeast corner across to the southwest. Then push the crate in the northwest corner across the room so it toches the iced crate. Stand behind the crate you just pushed and push it to the south. Then push the same crate westone space so it hits the first crate. Now push the crate one more time south and the switch will be activated. The second time you need to enter the room is different. start by pushing the crate to the north south. Go to the south and shove the crate to the middle of the puzzle so it passes over the middle floor switch. Now shove the crate that's on the eastern edge west then north. So Its sitting in front of the middle floor switch. Run to the crate that's furthest north and push it clockwise around the rim of the puzzle so it hits the crete you have yet to move. Finally face north and push the crate so it is on the switch leading upstairs.
It really depends. On the person and the type of crate. I think you need to be alot more specsific about that one im afraid. Also depends on the size of the crate. Type of animal..... You get the point. Sorry.
