1. The problem statement, all variables and given/known data Find the acceleration of block A when moving downward Theta=40 degrees A=103N B=31N Static coefficient = 0.56 Kinetic coefficient = 0.25 2. Relevant equations F=ma Normal Force * Kinetic coefficient = Friction Force 3. The attempt at a solution From 103/9.8 I get a mass of ~10.5 Breaking 103 into components, 103sin40 and 103cos40, the first being perpendicular and the second being along the plane 103sin40*0.25=Friction Force Tension is 31, so the sum of forces is: (31+103sin40*0.25)-103cos40 = Fnet Fnet/10.5 = Acceleration of A is this correct? Thanks!
