Over the first four seconds, the rocket’s engines give it a velocity of 5t m/s, where t is the time since liftoff. Over the next five seconds, the rocket continues to move vertically but is now pulled downwards by gravity, so has velocity 20 − 5t. Finally, a parachute unfurls and the rocket falls at velocity −10 + 5e−(t−9) for all t ≥ 9. How high up is the rocket 12 s after liftoff? What is the total distance the rocket travels? 2 ...
