A satellite is spinning at 0.01 rev/s. The moment of inertia of the satellite about the spin axis is 2000 kg * m^2. Paired thrusters are located at a distance of 1.5 m from the spin axis. They deliver their thrust in pulses, each thruster producing an impulse of 15 N * s per pulse. At what rate will the satellite be spinning after 30 pulses?
