Question

a bullet of mass 20 g is fired from a refile of 8 kg mass with a velocity of 100m/s .the velocity of recoil of the refile is​

Answer 1

$\huge\boxed{{{Answer:-}}}$

= m1 v1 = M2V2

= 20/1000 × 100 = 8 × V2

= 2 = 8 × V2

= V2 = 2/8 m/s

= V2 = 1/4 = 0.25 m/s

Therefore, the velocity of recoil of the refile is 0.25 m/s
