I'm sorry for posting another thread but I'm totally lost here..
A wheel and axle having a totel moment of inertia of 0.002kgm is caused to rotate about a horizontal axis by means of an 800g mass attached to a cord wrapped around the axle.
The radius of the axle is 2cm. Starting from rest, how far must the mass fall to give the wheel a rotational rate of 3rev/s?
