Problem 20PE

Unreasonable Results 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? (c) Which premise is unreasonable or which premises are inconsistent?

Step-by-Step Solution:

Step-by-step solution Step 1 of 9 (a) Calculate the kinetic energy of the car from relation, Here, M is mass of the car; V is velocity of the car.
