A small motor is mounted on the axis of a space probe with its
rotor (the rotating part of the motor) parallel to the axis of
the probe. its function of the probe about the axis. The moment
of inertia of the probe is 6200 times that of the rotor.
Initially, the probe and rotors are at rest. The motor is turned
on and after some period of time, the probe is seen to have
rotated by positive 32.6 degrees. Through how many revolutions
has the rotor turned.
