Here's another attempt, which yielded the right answer.
For m1:
m1ax=T-m1gsinθ
For m2:
m2(-ax)=T-m2g
m1ax+m1gsinθ=m2(-ax)+m2g
ax(m1+m2)=m2g-m1gsinθ
ax=(m2g-m1gsinθ)/(m1+m2)=(5*9.8-10*9.8*.64)/15=-0.92
I tried to write out the equations as follows:
m1ax=T - m1gsinθ
m2ax=T - m2g
Is this correct? Upon solving this I got an answer that is different than the one in the book
