At time t=0, a 2750 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 1.55 s is time, and has a magnitude of 781.25 N when t = 1.55s.
(a) Find the SI value of the constant A.
I solved this and found that A = 325 N/s^2.
need help with next two parts:::
***(b) What impulse does the engine exert on the rocket during the 1.50 interval starting 2.00 after the engine is fired?
***(c) By how much does the rocket's velocity change during this interval?
