The rotor of an electric motor has a rotational inertia \(I_m = 2.47*10^{-3} \; \mathrm{kg*m^2} \) about its central axis. The motor is mounted parallel to the axis of a space probe having a rotational inertia \(I_p = 12.6 \; \mathrm{kg*m^2} \) about its axis. Calculate the number of revolutions of the motor required to turn the probe through \(25.0^\circ \) about its axis.
