A space probe is traveling in outer space with a momentum that has a magnitude of 7.5 x 10^7 kg*m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 2.0 x 10^6 N and has a direction opposite to the probe's motion. Determine the momentum of the probe after the retrorocket ceases to fire.
