A space probe is traveling in outer space with a momentum that has a magnitude of 4.29 x 107 kg·m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.02 x 106 N and a direction opposite to the probe's motion. It fires for a period of 11.9 s. Determine the momentum of the probe after the retrorocket ceases to fire.
