Answer:

(B) the external forces acting during a collision can be neglected

Explanation:

Impulse is the product of force and time for which it acts. From Newton's second law, impulse is the change in momentum. In a collision of bodies, there is a change in velocity, either in direction or magnitude. Hence, there is a change in momentum and an impulse.

The forces between the object contribute to the impulse and cannot be neglected.

Since the forces act over a time interval, they may be time-dependent. In such cases, the impulse is not a rectangular pulse (which is the graph of a time-independent force).

Impulse calculations are performed in isolated systems. Hence, external forces are neglected.

The statement that describes impulse approximation is that (B) the external forces acting during a collision can be neglected

  • Impulse approximation can be regarded as the approximation used in the process of studying the collision of an incident particle that has a bound target particle, however the the binding forces on the target particle can be neglected during the collision.

  • Impulse provide a certain amount of force that is needed to apply at some specific time so there can be  a change in momentum.

  • During collision, the particle will sudden, forceful come together in direct contact. For example two vehicles colliding on the road.

Therefore, option B is correct.
