You have designed a rocket to be used to sample the local atmosphere for pollution. It is fired vertically with a constant upward acceleration of 18 m/s2. After 24 s, the engine shuts off and the rocket continues rising (in freefall) for a while. (Neglect any effects due to air resistance.) The rocket eventually stops rising and then falls back to the ground. You want to get a sample of air that is 17 km above the ground. a) What is the highest point your rocket reaches (in km)? (b) Determine the total time the rocket is in the air in seconds.

taking g=10m/s2 a. highest point reached = 4.1472 km. b.total time of flight = 43.2 sec. final velocity on reaching earth = 288m/s
