Answer:
B. F∆t
D. ∆p
Explanation:
Both formulas are correct. In fact, impulse is defined as the product between the force applied (F) and the time interval in which the force is applied (∆t
):
I = F∆t
So, option B. is correct. However, we see that this expression corresponds also to the change in momentum (option D)
in fact, we can rewrite the force as:
[tex]I=(ma)\Delta t[/tex]
but the acceleration can be rewritten as ratio between change in velocity and change in time:
[tex]I=m\frac{\Delta v}{\Delta t} \Delta t=m \Delta v = \Delta p[/tex]
which corresponds to the change in momentum.
