Now a new block is attached to the first block. The new block is made of a different material and has a coefficient of static friction μ = 1.01. What minimum mass is needed to keep the system from accelerating?

m1=8.8kg theta=34 k =159N/m
tension in rope of m1=17.8 coefficient of static friction= 0.41
so far I have tried 8.8*9.8*sin34 - 8.8*9.8*0.41*cos34 = T
T = 23.576 N
T m*9.8*sin32 = 0.94*m*9.8*cos 32
but that did not give me the right answer...

correction.... T=18.91
