Question:

An advertisement claims that an 800-kg car is aided by its 20.0-kg flywheel, which can accelerate the car from rest to a speed of 30.0 m/ s. The flywheel is a disk with a 0.150-m radius.

(a) Calculate the angular velocity the flywheel must have if 95.0% of its rotational energy is used to get the car up to speed.

(b) What is unreasonable about the result?
