A hunter fires a $6\mathrm{.}48$ g bullet from a $\mathrm{.}243$ calibre hunting rifle that has a barrel length of $0\mathrm{.}610$ m$,$ and muzzle velocity of $902$ m$/$s$.1.$ Assuming the bullet experiences a constant force along the length of the barrel, calculate the magnitude of the force the rifle exerts on the bullet.

Correct answer:

$4\mathrm{.}32$E$3$ N

$2.$ Calculate the magnitude of the recoil, that is$,$ the force the bullet exerts on the rifle, in lbs$.$

Correct answer:

$972$ lb

$3.$ What is the name of the force the rifle exerts on the hunter?

Incorrect answer:

reaction force

$4.$ Is the magnitude of this force equivalent to the recoil?
