1. The problem statement, all variables and given/known data A gangster fires a bullet (m1 = 30 g, v1 = 190 m/s) at Stupendous Man (m2 = 31 kg), but it simply bounces away elastically. If Stupendous man was standing on a frictionless surface, what is the change in speed of the bullet after striking stupendous man? Be careful with signs and units! 2. Relevant equations conservation of momentum, mv1+mv2=mv1+mv2 3. The attempt at a solution the man is not moving initially, and final, i got 0.183 for the final bullet speed but thats not right, Iam confused about how to find the final for the bullet?
