ηϖ1. The problem statement, all variables and given/known data 2. Relevant equations I=½MR2 PE=mgh 3. The attempt at a solution The first thing that jumped out at me was "uniform cylinder" so I went ahead and calculated the moment of inertia for the cylinder and got I=½(4.4)(.4)2 = .352 and held onto that. Then, I calculated the forces due to gravity of each mass that is pulling down on the string. Fmb = 48kg×9.8m/s2 = 470.4N I'm not sure if I do the same for ma because it's resting on the table, so is there a force pulling on the string creating tension? But the next thing I did was find the gravitational potential energy of mb: PE = mgh = 48kg×9.8m/s2×2.5m = 1176 J. I'm not sure if torque is needed, but I went ahead and calculated it anyways: T=F×r = 470.4N×.4m = 188.16 And that is all I can think to do. I'm not sure how the radius, inertia, mass, and other properties of the pulley affect the masses A and B that move up and down via the string over that pulley. Could I take the 1176 J of potential energy and set it equal to ½mv2? But what mass would I use? Mass of the system (A + B)? Solve for V? That seems too simple for this section, because we are learning about angular kinematics, torque...etc. I think I'm missing something. Thank you for your time and advice!
