An empty ore car coasts at a constant horizontal speed under an ore chute. Ore falls vertically into the car. What effect does the addition of the ore have on(adsbygoogle = window.adsbygoogle || []).push({});

(a) The kinetic energy of the loaded car? The book says the answer is the same as the unloaded car.

(b) The momentum of the loaded car? The book says: The ratio of the velocities is equal to the sqare root of the inverse ratio of the masses.

So there is more momentum but not more kinetic energy?
