A 15.0 kg bucket of water is suspended by a very light rope wrapped around a solid cylinder 0.300 m in diameter with a mass of 12.0 kg. The cylinder pivots on a frictionless axle through its centre. The bucket is released from rest at the top of a well and falls 10.0 m to the water.

a) What is the tension in the rope while the bucket is falling? my answer: 42.15N

b) With what speed does the bucket strike the water? my answer: 11.8m/s

c) What is the time of the fall? my answer: 1.69s

d) While the bucket is falling, what is the force exerted on the cylinder by the axle: my answer: 159.87N this is the one that i am really unsure of (and a))

2. Relevant equations

solved but unsure

3. The attempt at a solution

could someone who knows what there doing please check my answers, i wouldn't ask if it wasn't important.. thanks in advance.
