By analyzing the torque on the wheel we get:
Solving for T: 
On the object:
Replacing our previous value for T:
The relation between angular and linear acceleration is:
So,
Solving for α:
The linear acceleration will be:
And finally, the tension will be:
These are the values of all the variables: α, a, T
