An empty railcar (think box car in a train) has a mass of 35x10^3 kg. It is rolling down the track at a steady 25 m/s with no forces acting on it other than gravity and the normal force of the track on the wheels. As it passes under a grain chute, 50x10^3 kg of wheat is dropped into the railcar. Use momentum conservation. A. What is the initial momentum of the railcar? B. What is the total mass after the wheat is dropped into the railcar? C. What is the speed of the railcar after the wheat is dropped into the railcar?

a man of mass m1 = 70.0 kg is skating at v1 = 8.00 m/s behind his wife of mass m2 = 50.0 kg, who is skating at v2 = 4.00 m/s. Instead of passing her, he inadvertently collides with her.
