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.(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------------------------

it have cost me 3 hours,but i cann't write out the constraint equation .

help

thanks
