A bicycle with 0.80m -diameter tires is coasting on a level road at 5.6m/s . A small blue dot has been painted on the tread of the rear tire.
PartA:What is the angular speed of the tires?
Part B:What is the speed of the blue dot when it is 0.80m above the road?
Part C:What is the speed of the blue dot when it is 0.40m above the road?

A bicycle with 0.86-m-diameter tires is coasting on a level road at 5.87 m/s. A small blue dot has been painted on the tread of the rear tire. What is the angular speed of the tires? What is the speed of the blue dot when it is 0.86 m above the road? What is the speed of the blue dot when it is 0.43 m above the road?
A mountain bicycle with 26 inch (0.660 m) diameter tires (mass of 15 kg, mass of each tire is 1 kg) has a rider (mass of 100 kg). The rider travels along a flat road with a speed of 10.0 m/s. The road then goes uphill with a slope of 1.4 degrees. If the rider is not pedaling and you ignore friction and air drag, how far up the hill does the rider on the bike go?
The figure above shows the drive train of a bicycle that has
wheels 67.3 cm in diameter and pedal cranks 17.5 cm long. The
cyclist pedals at a steady cadence of 77.5 rev/min. The chain
engages with a front sprocket 15.2 cm in diameter and a rear
sprocket 8.00 cm in diameter.
(a) Calculate the speed of a link of the chain relative to the
bicycle frame. m/s
(b) Calculate the angular speed of the bicycle wheels. rad/s
(c) Calculate...
Two bicycle tires are set rolling with the same initial speed of 4.00 m/s along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 psi and goes a distance of 19.0 m ; the other is at 105 psi and goes a distance of 92.8 m . Assume that the net horizontal force is due to rolling friction only and take the...
Two bicycle tires are set rolling with the same initial speed of 3.10 m/s along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 psi and goes a distance of 19.0 m ; the other is at 105 psi and goes a distance of 92.5 m . Assume that the net horizontal force is due to rolling friction only and take the...
Two bicycle tires are set rolling with the same initial speed of 3.20 m/s along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 psi and goes a distance of 18.3 m ; the other is at 105 psi and goes a distance of 93.1 m . Assume that the net horizontal force is due to rolling friction only and take the...
A wagon is coasting at a speed VA along a straight and level road. When ten percent of the wagon’s mass is thrown off the wagon, parallel to the ground and in the forward direction, the wagon is brought to a halt. If the direction in which the mass is thrown is exactly reversed, but the speed of the mass relative to the ground remains the same, the wagon accelerates to a new speed VB. (a) Calculate the ratio VB/VA....
