## Homework Statement

## Homework Equations

Vb/a = Vb - Va

## 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?
