How would the kinetic energy of a flywheel ( a spinning disk) change if its rotational inertia was five times smaller but its angular speed was five times larger

Answer: This implies that it will be 5 times lesser than it was before

Explanation:

From kinetic energy = 1/2Iω²

where I = rotational mass

and ω = angular speed

1/2 x (5I) x (1/25ω²) = 1/5th of the original kinetic energy

This implies that it will be 5 times lesser than it was before.

Answer:This implies that it will be 5 times lesser than it was beforeExplanation:1/2Iω²This implies that it will be 5 times lesser than it was before.
