1. The problem statement, all variables and given/known data The block moves to the left with a constant velocity v. a)determine the distance x as a function of Q . b)determine the Angular velocity as a function of Q c)determine the Angular acceleration as a function of Q http://img98.imageshack.us/img98/3691/16293179.jpg [Broken] 2. Relevant equations 3. The attempt at a solution Here is how i find the distance x. tagQ=a/x -> x=a/tagQ . Can anybody help me a little bit how to find b). Is it enough just to find the 1-st and 2-nd derivative of x in order to find velocity and acceleration ?
