Homework Help: Physics

A 13 kg bucket of water is attached toa rope that is wound around a cylinder whose radius is 10.3 cm. A crank with a turning radius of 44.6 cm is attached to the cylinder.
If the bucket accelerates upwards at a rate of 1.21 m/s^2, then how much tension is on the rope?

Again, seems easy, but i need some help please!

There is more information that you need here. Just apply Newton's secnd law:
Net force = Tension - Weight
= mass * acceleration
