At time t=0 a 2150 kg rocket in outer space fires an engine that exerts an increasing force on it in the +x−direction. This force obeys the equation Fx=At2, where t is time, and has a magnitude of 889.66 N when t=1.25 s. What impulse does the engine exert on the rocket during the 2.9 s interval starting 2.00 s after the engine is fired?

A space probe is traveling in outer space with a momentum that has a magnitude of 4.96 x 10 kg.m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.93 x 10 N and a direction opposite to the probe's motion. It fires for a period of 10.7 s. Determine the momentum of the probe after the retrorocket ceases to fire. A 48.0-kg skater is standing at rest...
