1. The problem statement, all variables and given/known data A 500g pistol lies at rest on an essentially frictionless table. It accidentally discharges and shoots a 10g bullet parallel to the table. How far has the bullet moved by the time the gun has recoiled 2.00mm? 2. Relevant equations 0=m1v1+m2v2 m1v1= (m1+m2)Vf 3. The attempt at a solution well i tried the 0=m1v1+m2v2 formula and tried to substitute the value of v as s/t and then eliminating time, i rearranged it for the displacement value of the bullet and got a weird value of -.1 when the answer is 9.8cm i know now that this is the wrong way to approach it when i consider the conservation of momentum but i have no other ideas on how to do this or how to start it! if anyone does it would be most appreciated!
