A 10kg block is attached to a massless cord that doesn't stretch or sag which is wrapped around a disc-like wheel for which m=5kg, I=(1/2)mR^2. If the block is allowed to drop straight down held back only by the rotation of the wheel
a) What is the tension in the rope
b) What is the acceleration of the block
I know that the tension isn't just F=mg and so am thinking it is combined with the mass of the block but don't know how to go about it
