Question

I will mark u brainliest...but pls answer with explaination From a rifle of mass 4kg, a bullet of mass 50g is fired with an initial velocity of 35 m/s.Calculate the initial recoil velocity of the rifle.

Answer 1

Answer:

since there's no external force applied, momentum is conserved

therefore, initial momentum = final momentum

m1v1 = m2v2

0.05 x 35 = 4 x v

on solving we get v = 0.4375 m/s
