Question

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?

A leaf spring can deflect 5mm at a load of 250 N. The initial camber has its center's vertical position relative to its ends at 160 mm. When the vehicle it were attached in passes a speed bump and the camber deflected to 140 mm. Determine the work done on the spring by the speed bump in Joules. Assuming the spring constant remains constant in all those instances. ('
