Question

A bullet of mass 20g is fired from a pistol of mass 2kg with a horizontal velocity of 150m/s calculate the recoil velocity of the pistol

Answer 1

Hi user, this question is from Newton's third law of motion.
Use the given formula to solve it....
m1v1=m2v2

m1 : mass of bullet
m2: mass of gun
v1 : velocity of bullet
v2 : Recoil velocity of gun.

Put the values given in the question, you will definitely get the right answer.
