Which of the following expressions are correct for impulse? a. mvb. f∆tc. fvd. ∆p

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:

but the acceleration can be rewritten as ratio between change in velocity and change in time:

which corresponds to the change in momentum.
