      Дано:                                                                   Решение:

                А=(6;5)                                                         Sx=x-xo

                В=(13;-3)                                                      Sx=13-6=7

                S-?                                                                Sy=y-yo

                                                                                     Sy=-3-5=-8

                                                                                     S²=7²+(-8)²=(49+64)=113

                                                                                     S=10,6

Ответ:перемещение равно 10,6.

Дано:                                     Решение:

       А=(15,5;18)                                  Sx=x-xo
       В=(6;1,2)                                      Sx=6-15,5=-9,5
       S=?                                              Sy=y-yo
                                                           Sy=1,2-18=-16,8
                                                                               S²=(-9.5)²+(-16,8)²=372.49                                                                                                                          S=19,3
Ответ: перемещение равно19,3.
