1. A rope connecting a 10 and 20 lb weight passes over a cylinder. The rope-cylinder friction coefficient is 0.2. Rope mass, cylinder radius not given. 2. Solve for downward acceleration of the heavy 20 lb block 3. I'm confused because this problem doesn't give a mass for the rope, so I assumed we could neglect friction. Then after writing force/tension equations for both masses and combining them, I got 10.7 ft/s^2 as the answer, which isn't one of the options.
