The magnitude of the tension in the string between blocks B and C is . Assume that each block has mass . Part A What is the magnitude of the force? Part A.1 Acceleration of block B Part not displayed Part A.2 Acceleration of all three blocks Part not displayed Express the magnitude of the force in terms of . ANSWER: = Kinetic Friction in a Block-and-Pulley System Consider the system shown in the figure . Block A has weight and block B has weight . Once block B is set into downward motion, it descends at a constant speed. Assume that the mass and friction of the pulley are negligible. Part A
