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?

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...

A bicycle wheel is approximately a hollow cylinder with an outside radius of 37 cm, inside radius of 33 cm, and a mass of 0.75 kg. A child rolls a bicycle tire down the street to see how far it will roll. a) While the wheel is on a 5.14° degree slope (9%), what is the acceleration of the wheel? b) What is the minimum coefficient of friction for the wheel to roll on a 5.14°slope? c) Ignoring friction, how...

A bicyclist on an old bike (combined mass: 94 kg) is rolling
down (no pedaling or braking) a hill of height 129 m. Over the
course of the 309 meters of downhill road, she encounters a
constant friction force of 342 Newton. If her speed at the top of
the hill is 5 m/s, what is her speed at the bottom of the
hill?

Question 8 2 points Save A cyclist, riding a bicycle at an initial speed vo = 7.00 m/s, goes over a big bump on the road. The height of the bump is h = 2.00 m, and the top of the bump is circular, with a radius R = 4.00 m. The total mass the cyclist and bike is m = 80 kg. Neglecting friction and air resistance, and assuming that the cyclist is not pedaling, calculate: (a) the cyclist's...
