Question
Block
A has weight wa and block
B has weight wb. Once block
B is setinto downward motion, it descends at a constant speed. Assume thatthe mass and friction of the pulley are negligible. A cat, also of weight wb, fallsasleep on top of block
A. If block
B is now setinto downward motion, what is the magnitude of itsacceleration? Express your answer in terms of someor all of the variables wb, wa, and g(the acceleration due to gravity). A cat, also of weight wb, fallsasleep on top of block
