Four railroad cars, each of mass 2.50 x 104 kg, are coupled together and coasting along horizontal tracks at speed vi toward the south. A very strong but foolish movie actor, riding on the second car, uncouples the front car and gives it a big push, increasing its speed to 4.00 m/s southward. The remaining three cars continue moving south, now at 2.00 m/s. (a) Find the initial speed of the four cars. (b) By how much did the potential energy within the body of the actor change?
My sister Crystal of mass M1=50kg is on an ice covered sidewalk with her dog Buster, who has mass M2=38kg. They are initially distanced d=5.00m apart. By pulling on the massless leash, my sister exerts a constant force F=30.00N on Buster, Buster slides towards her. How fast is Buster moving when he and my sister meet? (The leash is not rigid, so the distance can change between them. They also end at the same point, which means even if you cannot solve for their position, you can set them equal to one another)
