(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For some reason, I just can't seem to understand this question. I didn't think it would be this bad. Anyways, A Rocket fires from rest with an upward acceleartion of 30 m/s^s for 2 seconds. After this time the engine shuts off and the rocker freely falls back to the surface of the Earth. ( use g = 10 m/2^s)

a) Draw a v vs t graph. I've done that already. ;'D

b) Determine the height of the rocket when the engines shut off. Done.

c) Determine the Maximum height that the rocket reaches.<--- Okay. THis is the one. <--- For some reason I'm thinking that at the crest of the curve/line/ place before it falls its V = 0, but I have no idea how to figure out how much farther/higher it goes. And that is my problem.

2. The attempt at a solution

I've tried using, x = 1/2at^2+VoT+Xo and V^2 = Vo2+2AX.

But neither are right. Or I'm doing something wrong. D:

THanks in advance for any help or comments. :'D
