Question: Boxes A and B are at rest on a conveyor belt that is initially at rest. The belt is suddenly started in an upward direction

Boxes A and B are at rest on a conveyor belt that is initially at rest. The belt is suddenly started in an upward direction so that slipping occurs between the belt and the boxes. Knowing that the coefficients of kinetic friction between the belt and the boxes are ((k)A = 0.30 and ((k)B = 0.32, determine the initial acceleration of each box.
