I've been trying to solve this and cannot seem to be getting the right answer.. please help!!

A rocket is fired vertically with an upward acceleration of 19 m/s2. After 30 s, the engine shuts off and the rocket then continues rising (while in free-fall). The rocket eventually stops rising and then falls back to the ground.

a) What is the highest point the rocket reaches?

b) what is the total time the rocket is in the air?

c) what is the speed of the rocket just before it hits the ground?

Thanks!!
