In the diagram, the pulleys and the strings are massless. The strings do not stretch. The masses of the suspended blocks are m1 and m2, as shown. The magnitudes of the accelerations of the blocks are a1 and a2, respectively. I'm having trouble assigning the conventions for the variables. I assigned the motion downwards as positive.
1. Homework Statement
T1 = The string connecting m2, and the string connecting the two pulleys.
T2 = Left string connecting the left pulley.
a1 = acceleration of mass 1
a2 = acceleration of mass 2
m2
m1
Homework Equations
Result of FBD:
T1 + m2g = m2a2
T2 + T1 - m1g = - m1a1

So... I can't isolate a1 in terms of a2.
