The 1400-kg mass of a car includes four tires, each of mass (including wheels) 34 kg and diameter 0.80 m. Assume each tire and wheel combination acts as a solid cylinder.

A. Determine the total kinetic energy of the car when traveling 92 km/h .

B. Determine the fraction of the kinetic energy in the tires and wheels.

C. If the car is initially at rest and is then pulled by a tow truck with a force of 1400 N , what is the acceleration of the car? Ignore frictional losses.

D. What percent error would you make in part C if you ignored the rotational inertia of the tires and wheels?

Two identical wheels are moving on horizontal surfaces. The center of mass of each has the same linear speed. However, one wheel is rolling, while the other is sliding on a frictionless surface without rolling. Each wheel then encounters an incline plane. One continues to roll up the incline, while the other continues to slide up. Eventually they come to a momentary halt, because the gravitational force slows them down. Each wheel is a disk of mass 3.73 kg. On...
