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

Question

minhkhue · Answer

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 befor e.
