1. The problem statement, all variables and given/known data Three blocks on a frictionless surface are connected by strings like so (from left to right): Block 1 (m=10kg) to string with Tension 1 to Block 2 (m=20kg) to string with Tension 2 to Block 3 (m=30kg) to string with Tension 3. The blocks are pulled to the right with force T3=60N. Find T1 and T2. 2. Relevant equations I'm not even sure... maybe Fn=mg 3. The attempt at a solution I would guess T1 is 20N and T2 is 40N, because it's proportional to T3. But this doesn't seem correct. Could I please get some feedback? Thank you!
