# In a collision between two objects of identical mass, could the acceleration values be different?

No.

In a collision the force that body A exerts on body B will always be equal to the force that body B exerts on body A (Newton's third law). Therefore it follows that the rate of change of momentum will be equal for both A and B. Also because A and B have the same mass and experience the same rate of change of momentum, therefore the acceleration on each object will be equal.

Yes, the acceleration values could be different if the objects experience different net forces during the collision.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
