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 (μk)A = 0.8 and (μk)B = 0.82, determine the initial acceleration of each box. The initial acceleration of box A, aA, is ft/s2. The initial acceleration of box B, aB, is ft/s2.
![As shown in the figure, blocks of masses m1 = 268.9 g and m2 = 598.5 g are attached by a massless string over a frictionless and massless pulley. The coefficients of static and kinetic friction between the block and inclined plane are 0.250 and 0.123, respectively. The angle of the incline is θ = 27.1∘, and the blocks are at rest initially. What is the acceleration of the blocks? [Answer with a negative number if m2 moves downward, and a positive number if it moves upward. ] Submit Answer Incorrect.
