An astronaut is in space, initially at rest. He then rotates a 1 kg mass around their head on a 2 meter long string. It rotates at a rate of 1 revolution per second in the counter-clockwise direction as shown. If the moment of inertia of the astronaut is 2 kg m^2, what will the angular velocity of the astronaut be?
