1. The problem statement, all variables and given/known data A pulley (in the form of a uniform disk) with mass 79 kg and a radius 14 cm is at- tached to the ceiling in a uniform gravita- tional field and rotates with no friction about its pivot. The masses are connected by a massless inextensible cord. Determine the acceleration of the mass 33 kg. The acceleration of gravity is 9.8 m/s2 . Assume up is positive. Answer in units of m/s2. 2. Relevant equations Net Torque = Moment of Inertia *Angular Acceleration Torque = Force * Radius 3. The attempt at a solution I attempted this: I*Alpha = net toque 1/2MR^2*(A/R) = (56-33)*9.8*R M*A=23*9.8*2 A=(23Kg*9.8m/s/s*2)/(79Kg) Unfortunately that didnt work... Thanks for any help.
