Finding mass with forcce and speed

  1. Sep 21, 2008 #1
    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

    ...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!
