As per guidelines , only 3 subparts are solved here. Given, mass of first train car , m1 = 1.50×105 kg mass of second train car , m2 = 1.10×105 kg Initial speed of first car , v1,i = 0.30 m/s Initial speed of second car , v2,i = -0.12 m/s Friction is negligible. 1. The is no external force acting on this two car system. So linear momentum of two car system remains conserved. Hence , linear momentum of two car system remains same before and after collision. 2. The collision in which two objects stick together , is perfectly inelastic collision. So this is perfectly inelastic collision. Kinetic energy of two car system doesn't remains same because kinetic energy is lost in binding the two car together. 3. Let the final velocity be vf. From conservation of linear momentum. m1v1,i + m2v2,i =(m1+m2)vfvf =m1v1,i + m2v2,im1+m2

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 = 0.30m/s, and the second having a mass of
1.10×105kg and a speed of
V2,i = 0.12m/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.
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?
