11.2 Boxes A and B are at rest on a conveyer belt that is initially at rest. The belt suddenly starts
in an upward direction so that slipping instantly occurs between the belt and the boxes. The
kinetic friction coefficients between the belt and the boxes are μk,A = 0.3 and μk,B = 0.32.
Determine the initial acceleration of each box. Will the blocks stay together, or separate?

15°
Hint: to see if the boxes stay together or separate, first assume they separate, and see if their
resulting motion (acceleration) validates that assumption. If the their motion is not consistent
with the assumption of separation, then they must stay together.
