A spacecraft is in empty space. It carries on board a gyroscope with a moment of inertia of I, = 21.5 kg m2 about the axis of the gyroscope. The moment of inertia of the spacecraft around the same axis is 1̟ = 5.00 x 105 kg m². Neither the spacecraft nor the gyroscope is originally rotating. The gyroscope can be powered up in a negligible period of time to an angular speed of 140 rad/s. If the orientation of the spacecraft is to be changed by 21.0°, for what time interval should the gyroscope be operated?
