Coupling of train cars is a regular feature at railway yards. Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 1.50×105kg and a speed of v1,i = 0.65m/s, and the second having a mass of 1.10×105kg  and a speed of  v2,i = 0.25m/s.  Assume that the friction between the train tracks and the train cars is negligible.

Question

Coupling of train cars is a regular feature at railway yards. Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 1.50×105kg and a speed of v1,i = 0.65m/s, and the second having a mass of 1.10×105kg  and a speed of 
v2,i = 0.25m/s.  Assume that the friction between the train tracks and the train cars is negligible.

 

 

  1. Consider our system to be the two train cars. Is linear momentum of the two-car system the same before and after the collision? Explain why?
  2. What type of collision is this? Is kinetic energy of the two-car system the same before and after the collision? Explain why?
  3. Solve for the final velocity of the two coupled trains symbolically.
  4. Calculate the final velocity of the two coupled trains using the numerical values provided.
  5. If we consider our system to be a single car, is the momentum of a single car system the same before and after the collision? Why?
