6. For the first five seconds after take-off the rocket engine can deliver a net acceleration a with magnitude a = ct² + b, where c = 6.66 m/s4 and b = 18.1 m/s?. (Note: since this is net acceleration, we include the contribution of gravity into this acceleration) What is the speed of the rocket 1.65 seconds after take off ?
