_____________________________________________________________

Here                  

                                      Initial velocity of bulllet (u) =50 m/s
                                      Final velocity of the bullet (v)= 0 m/s
                                       Distance(s)=10 cm or 0.1 m
                                       Retardation/accleration (a)=?

Using equation                 v²=u²+2as

                                         0²=50²+2×a×0.1

                                         0²=2500+0.2a

                                        -2a=2500
                                        10

                                         - 2a=25000

                                        -a=12500

                            Thus a= -12500 m /s²

Hence the retardation produced in bullet is 12500 m/s²
