1. The problem statement, all variables and given/known data If a1 and a2 are the accelerations of m1 and m2, respectively, what is the relation between these accelerations? 2. Relevant equations Link to the diagram : http://www.webassign.net/serpop/p4-38.gif 3. The attempt at a solution The answer is a1 = 2*a2, but I'm having trouble visualizing/understanding how it was gotten. Is there a specific way to do this?
