A space probe is traveling in outer space with a momentum that has a magnitude of 7.70 107 kg · m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 2.20 106 N and a direction opposite to the probe's motion. It fires for a period of 11 s. Determine the momentum of the probe after the retrorocket ceases to fire.
