Homework Help: How to get the constraint equation of this problem

  1. Dec 20, 2006 #1
    A particle moves in the xy plane under the constraint that its velocity vector is always directed towards a point on the x axis whose abscissa is some given function of time f(t). Show that for f(t) differentiable, but otherwise arbitrary, the constraint is nonholonomic.
    --------------------------------------------
    it have cost me 3 hours,but i cann't write out the constraint equation :confused: .
    help
    thanks
