What is the total kinetic energy before the collision? After?

What is the velocity of each train at minimum separation?

What is the total kinetic energy at minimum separation?

How much energy is stored at minimum separation?

What is the minimum separation distance between the trains? Hint: The energy temporarily stored at minimum separation equals a portion of the area under the above graph. The collision starts when the centers of the trains are separated by 0.03 m as shown on the above graph at which time the collision force is 15 N. But this force increases to 30 N and then eventually 45 N.

What is the magnitude of the force acting on each mass at minimum separation?
