At time t = 0 a 2130 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=At^2, where t is time, and has a magnitude of 781.25 N when t = 1.27 s. A. What impulse does the engine exert on the rocket during the 1.50 s interval starting 2.00 s after the engine is fired? (Please specify units) B. By how much does the rocket's velocity change during this interval? Assume constant mass.
