1. The problem statement, all variables and given/known data 2. Relevant equations Vb/a = Vb - Va 3. The attempt at a solution I got as far as realizing that the velocity of B depends on A so I wrote out: 2(Xa) + (Xb/a)cos15 = constant and took the derivative of that equation to get Vb/a = -16.56. I then got stuck as to how to get Vb. Is Vb/a in the direction of the rope pulling on B and would Vb be in that direction too? Also since Vb/a is at an incline, how would i put it into the relative velocity equation to account for two velocities at incline?
