An initially installed flywheel can store 10⁶ J of kinetic energy when rotating at 300 rad/s.It is replaced by another flywheel of the same size but made of a stronger material.If its mass is the same as that of the original,and it is now capable of achieving a rotational speed of 425 rad/s,what maximum energy can be stored? A)2.01E+6 J B)1.66E+3 J C)1.73E+5 J D)1.00E+6 J

Question

Quizplus · Accepted Answer

Kinetic energy is proportional to the square of angular velocity. So, the new maximum energy stored is:E = (425/300)^2 * 10^6 J = 2.01 * 10^6 J

An Initially Installed Flywheel Can Store 106 J of Kinetic
