1. The problem statement, all variables and given/known data The figure shows three blocks attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table; the masses are mA = 4.80 kg, mB = 7.10 kg, and mC = 13.0 kg. When the blocks are released, what is the tension in the cord at the right? Figure A is on the left, figure C on the right, C being the largest mass. 2. Relevant equations For part A I got T-m1g=ma, (Because the tension will be more used when it gets pulled up) For Part B, This is where i am confused, I originally used T1-T2=M2A, because I thought that since the Box B will move to the right, then its tension would be less because Box C is pulling more with M3g, but I checked the answer and it said T2-T1=M2A, but why is that the right answer For Part C I got, M3g-T=m3a (since gravity will do most of the work 3. The attempt at a solution I got the answer of -7.22 on my first attempt and 3.22 for the acceleration on the second, which 3.22 is the correct answer. Help!! I am just confused in part B!!
