What is the acceleration of an object if the velocity of am objects changes from 65 ms to 98 m/s during a time interval of 12 s?

Respuesta :

AL2006

Acceleration  =  (change in speed) / (time for the change)

Change in speed = (ending speed) minus (starting speed)

                            =      (98 m/s)   -   (65 m/s)   =   33 m/s

Acceleration  =  (33 m/s) / (12 sec)  =  2.75 m/s²
