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.
