I don't know how to begin solving this problem so any suggestions on how to go about solving it would be greatly appreciated. 1. The problem statement, all variables and given/known data The rope connecting slider A and mass B passes over two small pulleys, one of which is attached to A. Mass B has a constant velocity v_0, directed downwards. At the instant when y_A = b, determine: (a) velocity of A, and (b) acceleration of A.

Relevant equations The equations that I think I need to use include the ones from rectilinear motion such as v = ds/dt, a = dv/dt. 3. The attempt at a solution The only thing that I know is that this is a first degree problem because there are two moving objects (A and B) and the rope is the constraint.
