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 ([tex]\Delta t[/tex])
[tex]I=F \Delta t[/tex]
Using Newton's second law (F = ma), we can rewrite the force as product of mass (m) and acceleration (a):
[tex]I=(ma) \Delta t[/tex]
However, the acceleration is the ratio between the change in velocity ([tex]\Delta v[/tex]) and the contact time ([tex]\Delta t[/tex]): [tex]a=\frac{\Delta v}{\Delta t}[/tex], so the previous equation becomes
[tex]I=m \frac{\Delta v}{\Delta t}\Delta t[/tex]
And by simplifying [tex]\Delta t[/tex],
[tex]I=m \Delta v[/tex]
which corresponds to the change in momentum of the object.
