(10-79) The 1100-kg mass of a car includes four tires, each of mass (including wheels) 35 kg and diameter 0.80 m. Assume each tire and wheel combination acts as a solid cylinder. Determine (a) the total kinetic energy of the car when traveling 95 km/h and (b) 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 1500 N, what is the acceleration of the car? Ignore frictional losses. (d) What percent error would you make in part (e) if you ignored the rotational inertia of the tires and wheels?

The M is meant to be the mass of the chassis + wheels, not the mass of the chassis alone. Indeed on the book the result for point (a) is 4.1*10^5 J
