Homework Help: Partical Experiencing a Force

  1. May 4, 2010 #1
    1. The problem statement, all variables and given/known data
    A 600 g particle moving along the x-axis experiences the force shown in the figure . The particle's velocity is 2.0 m/s at [tex]x = 0\:{\rm{ m}}[/tex].

    2. Relevant equations



    3. The attempt at a solution
    To be completely honest, I don't have a clue on how to even start this problem. I tried to use the 1D kinematic equations, but that didn't result in anything useful because I don't know the acceleration. I tried to find the acceleration with F=ma, but that still didn't make much sense. If I could get a nudge in the right direction, that would be awesome.

    I know the answer is 6.8 m/s, but I do not know how to go about solving for that.

    Hi tangibleLime! :smile:

    Use work done = ∫ (force).(distance), and the work-energy theorem. :wink:
