The recoil velocity will be 5.42 m/s.

How is Newton 3rd law stated ?

Newton 3rd law state that in every action, there will be equal and opposite reaction.

Given that a  rifle bullet of mass 60.0 g leaves the muzzle of a rifle with a velocity of 2.8 x 10² m/s. If the rifle has a mass of 3.1 kg, with what velocity will it recoil ?

The parameter given are;

  • mass of the bullet m = 60g = 0.06Kg
  • Velocity of the bullet u = 2.8 x 10² m/s
  • mass of the rifle M = 3.1 kg
  • Recoil velocity v = ?

mu = Mv

Substitute all the parameters

0.06 × 2.8 × 10² = 3.1 v

16.8 = 3.1v

Make v the subject of formula

v = 16.8/3.1

v = 5.42 m/s

Therefore, the recoil velocity will be 5.42 m/s.
