The 1100-kg mass of a car includes four tires, each of mass(including wheels) 35kg and diameter 0.80m. Assume each tire andwheel combination acts as a solid cylinder.
Determinea) the total kinetic energy of the car when traveling 95km/hb) the fraction of the kinetic energy in the tires and wheelsc) If the car is initially at rest and is then pulled by a towtruck with a force of 1500N, what is the acceleration of the car?(Ignore frictional losses)d) What % error would you make in part (c) if you ignored therotational inertia of the tires and wheels?
