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 .
