A bullet with mass 60.0 g is fired with an initial velocity of 575 m/s from a gun with

mass 4.50 kg. What is the speed of the recoil of the gun?

2 answers

(massbullet * velocitybullet)/massgun
(60.0 * 575/4.50) = 7666.66666
Which rounded off becomes 76.7m/s
you didn't convert G into KG, so the answer would be 7.67m/s
