A car starts from rest and accelerates along a straight line path in one minute it finally attains a velocity of 40 meters/second what is the cars average acceleration

Answer :

sdbeltran17
|Average acceleration| = (change in speed) / (time for the change)

Change in speed = (speed at the end) minus (speed at the beginning)

                            =        (40 m/s)            -            ( 0 )

                            =   40 m/s .

|Average acceleration| =    (40 m/s)  /  (60 sec)  =  2/3  m/s² .
