A curling stone has a mass of 18.0 kg. The stone begins initially at rest on a flat ice surface. It is then pushed by a curler at a constant horizontal force of magnitude 24.0 N over a distance of 4.00 m. If you were to make any friction between the stone and ice negligible - how much power is applied by the person pushing the stone at the beginning of the push, and how much is applied at the end of the push?
