## Homework Statement

A 110 kg fullback is running at 4.4 m/s to the east and is stopped in 0.75 s by a head-on tackle by a tackler running due west.

A. Calculate the impulse exerted on the fullback.

B. Calculate the impulse exerted on the tackler.

C. Calculate the average force exerted on the tackler.

## Homework Equations

Fnet*delta time = change in momentum

## The Attempt at a Solution

To solve A I set up the equation like this

.75X= 110 * 0 + 110 * 4.14

.75x=484

divide by .75 and you get

645.33 Ns

This is not right but I'm not sure why. Did I calculate the change in momentum incorrectly?

I'm not sure how to find the impulse on the tackler because I don't have his mass given to me and I don't have his velocity .
