A new question, hard one.

  1. Nov 16, 2009 #1
    1. The problem statement, all variables and given/known data
    the motion of a particle of mass m=10kg is described by the equation x= y=
    where x and y are in meters and t in seconds. Determine the velocity acceleration of the particle and the force acting on it.


    2. Relevant equations



    3. The attempt at a solution

    oh sorry. there is no any eq in front of x and y, can u put one for me and explain it for me

    Again, you'll want to formulate an equation that gives the position function, and relate that to velocity, then relate that equation to acceleration, at which point you can use Newtons second law to figure out the force acting on the particle.
