In this problem, the fact that the length of the string does not change imposes a constraint on relative accelerations of the two blocks. find a relationship between the x component of the acceleration of block 2, a2x, and the acceleration of block 1. pay careful attention to signs. express a2x in terms of a1x and/or a1y, the components of the acceleration vector of block 1.
