A 0.45-kg football traveling at a speed of 22 m/s is caught by an 84-kg stationary receiver. If the football comes to rest in the receiver's arms, what is the magnitude of the impulse imparted to the receiver by the ball?

Recall,

#"Impulse" = FDeltat = Deltap#

If the football comes to rest, its momentum is conserved and the impulse represents its original momentum.

Hence,

#Deltap = mnu = (9.9"m" * "kg")/"s"#

is the impulse imparted to the receiver by the ball, regardless of the receiver's mass.
