Recoil Formula?

When people are shot in the movies, the blast often knocks them backwards. Is this realistic? If a 20.0 gram bullet (which is a large bullet) traveling at 870 m/s strikes a 80.0 kg man wearing a safety vest, how fast in meters/second will the man be knocked backwards? Assume it is an inelastic collision because... show more When people are shot in the movies, the blast often knocks them backwards. Is this realistic? If a 20.0 gram bullet (which is a large bullet) traveling at 870 m/s strikes a 80.0 kg man wearing a safety vest, how fast in meters/second will the man be knocked backwards? Assume it is an inelastic collision because the bullet sticks in the vest.
