1. The problem statement, all variables and given/known data A bullet of mass 0.0100kg moving horizontally strikes a block of M=5kg and becomes embedded. If the block bullet move a distance of 6 m on a rough horizontal table. The coefficient of kinetic friction is 0.300. What is the speed of the bullet before striking the block ? 2. Relevant equations m1v1= ( M+m) V2 - fkd (1) 3. The attempt at a solution I got two unknowns and one equation. I do not have V2 and v1 so l am stuck.
