Answer:
Collision force will be same in both the cases.
Explanation:
A perfectly inelastic collision is said to take place when a system loses the amount of its Kinetic Energy at its maximum. In a perfectly inelastic collision, the colliding particles stick to each other. In such a collision, kinetic energy is lost by combining the two bodies with each other.
In situation 1:
Speed of Car A,
Speed of Car B,
Relative speed of car A and car B,
Now, in the situation 2:
Speed of car A,
Speed of car B,
Relative speed of car A and car B,
Therefore, Car A and Car B both have the same relative speed, v = 10 m/s
