Be sure your derivation of the answer clearly contains the three steps described in lecture: For each object: (1) Free-body diagram, (2) choice of coordinate systems, and finally (3) for each object, equations ? Fx=max, ? Fy=may.

Explanation / Answer

Again a FBD for each m1: T-m1*g=m1*a1 Positive is upward m2: T-m2*g=m2*a2
