Textbook Question

Chapter 9, Problem 53P

* Flywheel energy for car The U.S. Department of Energy had plans for a 1500-kg automobile to be powered completely by the rotational kinetic energy of a flywheel. (a) If the 300 kg flywheel (included in the 1500-kg mass of the automobile) had a 6. 0-kg ⋅ m 2 rotational inertia and could turn at a maximum rotational speed of 3600 rad/s. determine the energy stored in the flywheel. (b) How many accelerations from a speed of zero to 15 m/s could the car make before the flywheel's energy was dissipated, assuming 100% energy transfer and no flywheel regeneration during braking? Ignore rotational kinetic energy of car wheels.
