Answer:
B) the change in momentum
Explanation:
Impulse is defined as the product between the force exerted on an object (F) and the contact time ()
Using Newton's second law (F = ma), we can rewrite the force as product of mass (m) and acceleration (a):
However, the acceleration is the ratio between the change in velocity () and the contact time (
):
, so the previous equation becomes
And by simplifying ,
which corresponds to the change in momentum of the object.
