Question

A 15 kg crate of apples is sitting a rest on the floor of the classroom. The coefficient of friction between the crate and the floor is μₛ=0.55 and μₖ=0.43. A student begins to apply a force on the crate, slowly increasing the force until the crate moves.

A. Construct a free-body of the situations below BEFORE the crate begins to move.

B. What force will allow for the crate to initially be set in motion?

C. Construct a free-body diagram of the situation AFTER the crate has begun to move.

D. Once the crate begins to move, the student continues to apply the same amount of force as what was required to move it. Determine the acceleration of the crate.
