Blocks A, B, and C are placed as in the figure and connected by ropes of negligible mass. Both A and B weigh 24.9N each, and the coefficient of kinetic friction between each block and the surface is 0.39. Block C descends with constant velocity.

a) Find the tension in the rope connecting blocks A and B.

b) What is the weight of block C?

c) If the rope connecting A and B were cut, what would be the acceleration of C?

The attempt at a solution

I figured out part (a), 9.71N. I am stuck and have a mental block and can't get the weight of block C to save my life. I used the equation:

T_{2}=T_{1}+wsin[tex]\Theta[/tex]+[tex]\mu[/tex]N_{B}

which yielded a result of 34.37N, which I know is incorrect. The answer in the back of the book is 30.8N, but the coefficient of friction and weights are different.
