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

A 200 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 33 m/s^2 for 34 s, then runs out of fuel. Ignroe any air resistance effects.

A) what is the rocket's maximum altitude?

B) how long is the rocket in the air?

2. Relevant equations

i tried using vf=vi + at for part a and then i think i use the equation d=vi*t+1/2*a*t^2 to find the altitude.

3. The attempt at a solution

for vf, i got 1122 m/s, but i'm not sure if this is right or if i'm using the right equations. if that is correct, i plug it into the 2nd equation to get my second answer, right?

if anyone can help, i would really appreciate it :)
