12. unmanned space probe a 2500 kg unmanned space probe is moving in a straight line at a constant speed of 300 m/s. control rock- ets on the space probe execute a burn in which a thrust of 3000 n acts for 65.0 s. (a) what is the change in the magnitude of the probe’s translational momentum if the thrust is backward, forward, or di- rectly sideways? (b) what is the change in kinetic energy under the same three conditions? assume that the mass of the ejected burn products is negligible compared to the mass of the space probe.
