## The Attempt at a Solution

Ok i got a, b, and c. But i need help with d.

My attempt was to find the force of block b - Tension of block C

block B = sin(36.9)25 - the force on block b

cos(36.9)25*0.35 - which is the friction.

block C = 30.8N (which I got from part c)

Then I took the force on C-B which I got 22.787N but then tried to divide by the mass to get acceleration. This is there I'm confused. Please help me out and thanks in advance.
