In the foyer of Random Chemical Supply Company, there is a train set. My manager's children are allowed to play with it. They have a game. They put a glass of pickle juice on one of the train cars. They put the car with a glass full of pickle juice next to the post office in the train set. The track goes straight toward a wall from the post office. Then they start an engine from another part of the track. It moves at 3 m/s. When the engine hits the car, the bumper on the engine acts like a spring connecting the two. The bumper does not act like a spring until the collision, but it acts like a spring for all times after the collision. Every time they do this, the car hits with wall with nonzero velocity and the pickle juice spills. This is driving me nuts! Do you know how I could change the situation so that the juice does not spill? I think I could change the mass of the engine. Is there a mass that would allow the kids to play but stop the juice from spilling? If not, is there another method you would recommend? Here is some useful information. If this car hits the wall with nonzero velocity, the juice will spill. The car laden with pickle juice has mass 1 kg. The engine moves at 3 meters/ second and (currently) has mass 2 kg. The bumper has spring constant 2N/m. The post office is 10 meters from the wall. In the foyer of Random Chemical Supply Company, there is a train set.
