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 781.25 N when t = 1.25 s. a) Find the SI value of the constant A, including its units. b) What impulse does the engine exert on the rocket during the 1.50 s interval starting 2.00 s after the engine is fired? c) By how much does the rockets velocity change during this interval?
