Question

A bullet with a mass of 5.00 x 10^-3 kg is loaded into a gun. The loaded gun has a mass of 0.52 kg. The bullet is fired, causing the empty gun to recoil at a speed of 2.1 m/s. What is the speed of the bullet?

Answer 1

For the answer to the question above,
220 m/s
mass of the bullet * velocity of the bullet = mass of the gun * velocity of the gun
0.005 kg * v = 0.52 kg * 2.1 m/s
-> v = (0.52kg * 2.1 m/s) / 0.005 kg = 218.4 m/s
I hope my answer helped you. Have a nice day!
