# Finding mass with forcce and speed

1. The problem statement, all variables and given/known data
I need to find the mass of the enterprise.
I have the given...
2 pods (pulling the enterprise) : F=2500kdyn each.
t1 : v1 = 0.62km/s
t2: v2 = 12km/s
Time between those statements : (delta)t=11s

2. Relevant equations

v=m/s
...I don't know which equation to use, everything I have found to find mass or acceleration needs each other figured out first, which is impossible.

3. The attempt at a solution

Force at 50newtons.
I am math/physics dumb and haven't taken this stuff in years. I need a place that will show me a walkthrough because I don't know WHERE TO START.

I'm pretty dumb at physics too but here is the way I look at it. You are given two speeds, and a time, which then you can use the acceleration formula. a = (Vf-Vi)/(t). Now you are given a force and found acceleration, F=MA. Solve for mass.

All figured out, thank you!
