Hi there!

Recall that:

Impulse = Ī” in momentum = mĪ”v

Impulse = Force Ā· time

Begin by calculating the change in momentum, or impulse.

I = mĪ”v = m(vf - vi)

I = (79)(0 - 32) = -2528 Ns

Now, we can use the equation relating force and time to impulse.

I = Ft

Rearrange for time:

I/F = t

-2528/0.25 = -10112 N

**OR, if magnitude ā‡’ |-10112| = 10112 N
