Find how much total kinetic energy does the wheel have

Reference no: EM13505022

a bicycle racer is going downhill at 11.0 m/s when, to his horror, one of his 2.25 kg wheels comes off when he is 75.0 m above the foot of the hill. we can model the wheel as a thin-walled cylinder 85.0 cm in diameter and neglect the small mass of the spokes.

A) how fast is the wheel moving when it reaches the foot of the hill if it rolled without slipping all the way down?

B) how much total kinetic energy does the wheel have when it reaches the bottom of the hill?
