A space probe is traveling in outer space with a momentum that has a magnitude of 7.5e7 Kg*m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 2.0e6N and a direction opposite to the probe's motion. It fires for a period of 12s. Determine the momentum of the probe after the retrorocket ceases fire.
