A 10 kg crate is placed on a horizontal conveyor belt. The materials are such that Us = 0.5 and uk = 0.3. What is the maximum acceleration the belt can have without the crate slipping?

Answer:- a. The net force working in the vertical and horizontal directions is zero, as seen in the free body diagram. The static friction force is equivalent to and opposes the conveyor force.

b. The net force implemented in the vertical direction is zero in the free body diagram. The course of the kinetic friction force vector is conflicting to the direction that the conveyer belt is moving.
