Homework Statement
When the motor shown in the figure raises the m = 1050 kg mass, it produces a tension of 1.42×104 N in the cable on the right side of the pulley. The pulley has a moment of inertia of 79.8 kgm2 and a radius of 0.440 m. The cable rides over the pulley without slipping. Determine the acceleration of the mass. (Draw free-body diagrams of the mass and the pulley. Do not assume that the tension in the cable is the same on both sides of the pulley.)

I=(1/2)M*R^2 (for disks rotating about their center)
a_obj=|a_angular|*R
The Attempt at a Solution
Many people in my class are having problems completing this problem. I really didn't know where to start so I used the pulley's moment of inertia to calculate it's mass, but from there I don't know where to go. The different tensions on either side of the pulley are also really racking my brain. Any help would be appreciated!
