Determining the Force acting on a Particle

  1. Nov 2, 2008 #1
    1. The problem statement, all variables and given/known data
    A particle of mass [​IMG] moves across the XOY plane following the equation:


    2. Relevant equations
    [​IMG]


    3. The attempt at a solution
    I'm totally clueless about this one.
    I know I have to find the derivative of the movement equation to find the velocity and then again to find the acceleration and use it on Newton's Second Law of motion.
    (The previous exercise was the reverse problem, given the F(t) eq, find the x(t) eq.)
    I tried t=0 and t=1, and given the resulting vectors the velocity could be found? :frown:
