Answer:
Momentum of first train car will reduce
Explanation:
When the moving care collides with the stationary car, it will increase the momentum of the stationary car. However, its own momentum will reduce.
It is so because the speed of the first train car will reduce after collision due to loss of energy in the collision while the stationary car may gain some momentum due to rise in velocity from zero (velocity at stationary position).
