I've been stuck on this problem for a while. Im not sure where to even begin. A bike wheel is rotating with an angular velocity of 3.1 rev/s. If the coefficient of kinetic friction between the wheel and brakes is .87, then find the revolutions the wheel makes in coming to rest...

a track is mounted on a large wheel that is free to turn with negligible friction about a vertical axis. a toy train of mass m is placed on the track and, with the system initially at rest, the electrical power is turned on. the train reaches a steady speed v with respect to ...

A beetle sits at the top of a bicycle wheel and flies away just before it would be squashed. Assuming that the wheel turns clockwise, the beetle's angular displacement is 3.14 radians, which corresponds to an arc length of 1.2 m. What is the wheel's radius?

A potter’s wheel of radius 53.13 cm and mass 106.4 kg is freely rotating at 47.1 rev/min. The potter can stop the wheel in 5.65 s by pressing a wet rag against the rim and exerting a radially inward force of 66.2 N. What is the angular acceleration of the wheel?

A bicycle wheel of radius .7m is rolling without slipping on a horizontal surface with an angular speed of 2 rev/s when the cyclist begins to uniformly apply the brakes. The bicycle stops in 5 s. Through how many revolutions did the wheel turn during the 5 s of braking? I ...
