Crate on a conveyor belt..?
A 11 kg crate is placed on a horizontal conveyor belt. The materials are such that u s = 0.55 and u k =0.26. What is the maximum acceleration the belt can have without the crate slipping? How would you draw a free body diagram of the forces acting on the crate (what would it look like?) I know that gravity pulls downward on the crate, but which direction is the normal in, and friction?
