what is true about impulse pairs?

• impulse pairs will sometimes cancel out if the objects have the same mass.
• impulses dont occur in pairs.
• impulse pairs always cancel because they are equal in magnitude.
• impulse pairs never cancel because they are being applied to different objects.

Explanation:

Impulse pairs arise from Newton's third law: when two objects interact, the impulse exerted on object A by object B is equal in magnitude and opposite in direction to the impulse exerted on object B by object A. However, these impulses act on separate objects, so they cannot cancel each other out (cancellation only occurs when forces/impulses act on the same object).

Answer:

D. Impulse Pairs never cancel because they are being applied to different objects.
