Answer:Acceleration = (final velocity - initial velocity) / timeFinal velocity = 140 m/sInitial velocity = 0 m/sTime = 4.7 seconds Acceleration = (140 m/s - 0 m/s) / 4.7 seconds Acceleration = 140 m/s / 4.7 seconds [tex]acceleration \: = 29.79 \: ml {s}^{2} [/tex]Therefore, the acceleration of the car is approximately 29.79 meters per second squared.
