different forces for different amounts of time.
|
|
|
the same force for different amounts of time.

Explanation:
Detailed explanation-1: -Yes. The two objects experience the same force (NIII) and impact time, so they have the same impulse. Impulse equals the change in momentum, so the two objects have the same change in momentum.
Detailed explanation-2: -If two objects make a head on collision, they can bounce and move along the same direction they approached from (i.e. only a single dimension). However, if two objects make a glancing collision, they’ll move off in two dimensions after the collision (like a glancing collision between two billiard balls).
