Velocity question

  1. Feb 14, 2012 #1
    1. The problem statement, all variables and given/known data
    I have been given the force, mass and the time, and I need to find the velocity, and I only have the formula ##v=at##


    2. Relevant equations
    ##v=at##


    3. The attempt at a solution
    From the Newton's second law we know that ##a=\frac{F}{m}##,
    So Can I just do ##v=\frac{F}{m}t##, or do I need to find acceleration ##a##, then just go with the formula ##v=at##?

    They amount to the same thing.

    I don't think they amount the same on this task because i only been given the formula ##v=at## so we would define that formula as ##v=\frac{Ft}{m}##.

    Which, again, is the same thing algebraically.

    Maybe so, but how the task needs it to be, I think it's different

    I'm not sure what the distinction you're trying to make is.
