We are doing the Rocket lab in my Physics class, we shot rockets with different caps on them [ Low, Med, High ] and recorded the times. I have the time, i need to find Initial velocity and Height given that i have time. I also need to take into consideration air resistance [ Not sure, but i think i heard my teacher say that]

2. Relevant equations

I was thinking that if i did V = Accel*time, that would give me the velocity, but thinking that i need to include air resistance, would i need to start doing free body diagrams?

3. The attempt at a solution

If i did the diagrams that the net equations would be :

Fx = 0

Fy = n-g. [ Normal - Gravity]

I cannot think of any other factors to include, but the problem is i don't know how what to do now. I am stuck at the Fy equation.

Also, if there was no air resistance included, would i just do V = a*t to find my initial?
