The flywheel in a car is a solid cylinder with a mass of85 kg, a radius of 12 cm, and a length of 5.0 cm. It is rotatingabout an axis through its center (Table 11.2 (c)) at 3800 rpm (revolutions per minute).
(a) What is the kinetic energy of the cylinder?
J
(b) Suppose that all this rotational kinetic energy could betransformed into translational kinetic energy of the car, mass1200 kg. If the car started from rest,what would its final speed be?
m/s
