A 1.2 kg mass and a 7.1 kg mass are connected by a massless string over a pulley that is in the shape of a bicycle wheel (all mass is concentrated at the rim) having a radius 0.25 m and mass 4.6 kg. Determine the time for the masses to move 2.6 m starting from rest. A. 2.714 sec B. 0.223 sec C. 1.55 sec D. 1.68 sec E. 1.077 sec T1 = 7.1kg, T2 = 1.2kg T1 - m1g = -m1a T2 - m2g = m2a T1R - T2R = I(alpha) a=R(alpha) I was just wondering if I set these equations properly. I substituted and got an answer similar to E except its off a little even though I didn't round. Thanks in adv!
