A dockworker loading crates on a ship finds that a 24 kg crate, initially at rest on a horizontal surface, requires a 79 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 57 N is required to keep it moving with a constant ...

Physics
A 1200-N crate is being pushed across a level floor at a constant speed by a force of 260 N at an angle of 20.0° below the horizontal. (a) What is the coefficient of kinetic friction between the crate and the floor? (b) If the 260 N force is instead pulling the block at an...

physics
The force of friction between a crate and the floor it is sliding over depends on? a. the speed the crate is moving over the floor with b. the surface area of the crate in contact with the floor c. how much force you are exerting on the crate parallel to the crate's motion...
