Block A on the table isconnected to block B hanging beneath by a string of negligible mass which passesthrough the hole. Initially, B is held stationary and A rotates at constant radius ro withsteady angular velocity 0. If B is released at t = 0, what is its accelerationimmediately afterward?Two movable bodies and their free body diagrams:Cylindrical polar coordinate system.

How is mass related to weight, and how are the two concepts different?
