A wheel with moment of inertia \(m\) is mounted horizontally to a frictionless axle. At time \(t\) = 0 the initial angular speed is \(\omega\). A constant torque \(Q\) is applied to the wheel, bringing it to a stop in time \(t\). Which of the following is the average power required to dissipate the wheel's energy in this time?

W) m\(\omega\)/2t

X) m\(\omega\)/2t

Y) m\(\omega\)/t

Z) m\(\omega\)/Q
X) m\(\omega\)/2t
