Question

A rifle has a mass of 2.5 kg. if it is loosely gripped and a 1.5-g bullet is fired from it with a muzzle velocity of 1400 m/s. Determine the recoil velocity of the rifle just after firing.

Answer 1

Answer:

conservation of momentum

m1v1=m2v2

Explanation:

2.5×v1= 0.0015×1400

v1= 2.1/2.5= 0.84m/s
