Consider a bicycle wheel, radius ? with rim of mass ? and axle of mass ?. The masses of the wheel’s thin spokes are so small that we will neglect them. Initially, the wheel is resting on a horizontal surface, and you hold its axle, a hand on each side of the wheel, so that it doesn’t tip over. At time ? = 0? you exert a horizontal force of magnitude ? on the axle so that the wheel begins to roll without slipping.

a) Determine the wheel’s speed when you have pushed it forward a distance ?.

b) Determine the magnitude of the friction force that the surface exerts on the wheel while you push it.

With axle and spokes of negligible mass and a thin rim, a certain bicycle wheel has a radius of 0.350 m and weighs 33.0 N; it can turn on its axle with negligible friction. A man holds the wheel above his head with the axle vertical while he stands on a turntable that is free to rotate without friction; the wheel rotates clockwise, as seen from above, with an angular speed of 66.0 rad/s, and the turntable is initially at...

d Since the spokes of a bicycle wheel have much less mass than the rim, the wheel can be modeled as a cylindrical hoop of mass 1.90 kg and radius 0.6 m. This wheel rotates without friction about a vertical axis perpendicular to the disk and through its center. Standing on the rim is a kitten of mass 1.00 kg (the kitten can be modeled as a point mass). The wheel (with the kitten standing on it) rotates with an...

Consider an old-fashioned bicycle with a small wheel of radius 0.51 m and a large wheel of radius 0.8 m. Suppose the rider starts at rest, accelerates with a constant acceleration for 8 minutes to a velocity of magnitude 24.5 m/s. He maintains his velocity for 9.5 minutes and then decelerates, with constant deceleration, for 7.3 minutes. Find the total angle through which a point on the small wheel has turned.
