Answer:
(a). The kinetic energy stored in the fly wheel is 46.88 MJ.
(b). The time is 1.163 hours.
Explanation:
Given that,
Radius = 1.50 m
Mass = 475 kg
Power
Rotational speed = 4000 rev/min
We need to calculate the moment of inertia
Using formula of moment of inertia
Put the value into the formula
(a). We need to calculate the kinetic energy stored in the fly wheel
Using formula of K.E
Put the value into the formula
(b). We need to calculate the length of time the car could run before the flywheel would have to be brought backup to speed
Using formula of time
Hence, (a). The kinetic energy stored in the fly wheel is 46.88 MJ.
(b). The time is 1.163 hours.
