A professor is bored one day, so she goes to the rail-station. She finds an old rail car which only has one wall (but still has very well oiled (frictionless) wheels). She sits down on the rail car and realizes that she has a billiard ball in her pocket. She throws the billiard ball at the wall. It hits the wall and elastically recoils and shoots past the professor. Describe the motion of the rail car. (hint: draw a picture or two or three...)
