Acar traveling at 37 m/s starts to decelerate steadily. it comes to a complete stop in 6 seconds. what is its acceleration? m/s

Magnitude of acceleration = (change in speed) / (time for the change)

                            = (end speed - start speed)  /  (time for the change)

                            =  (0  -  37 m/s)  /  (6 sec)

                            =  ( - 37 / 6)  (m/s²)

                            =      - 6-1/6  m/s²

                            =     -6.1667 m/s²  (rounded) 

No because scientist are still changing there mines today so they are not correct to this day
