I'm actually trying to do this problem right now. I'm a bit stuck on the second part. How do you find the speed of the object at t = 2.0s? Every kinematic equation I've tried to use requires acceleration, and I can't find acceleration with having the final velocity... ahhh.

in other words we must use second law of newton to find acceleration, a=T/m but since we don't have tension we should utilise torque equation to find T, the point here is that we should notice angular acceleration=a/R2
