- 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? 80 lb 100 lb A B 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.arrow_forwardAn ideal gas is enclosed in a cylinder which has a movable piston. The gas is heated, resulting in an increase in temperature of the gas, and work is done by the gas on the piston so that the pressure remains constant. a) Is the work done by the gas negative, positive or zero? b) From a microscopic view, how is the internal energy of the gas molecules affected? c) Is the heat less than, greater than or equal to the work?
