Why is it not possible for a cone? Slide it up the (frictionless) cone with kinetic energy equal to mgh and it should stop on the point.

  It's the reverse of a point mass sliding up a hemispherical dome. It takes infinite time to reach the top.

  It never reaches the top in finite time on a cone, it just keeps going up and up getting slower and slower.

    That makes sense; thanks.
