Answer:
Wellll. I am assuming the direction of speed is in the same direction as the direction of displacement of the train. (i.e. Velocity is positive)

Explanation:
Answer:
A. Equal to and Opposite
Explanation:
when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .
Given that there are 2 bodies
Let P₁ as first object's momentum
P₂ as second object's momentum.
Total Momentum =P₁ + P₂
As there is no external force acying on the system
Change in the Total momentum is zero
so,
0 = Δ P₁ + ΔP₂
ΔP₂ = -ΔP₁
negative sign indicates opposite direction.
Both are of equal magnitude.
