Question: what is the formula for acceleration

  Options: 
 A. acceleration is the change in the velocity times speed, divided by the time. Acceleration has a magnitude (a value) and a direction. The direction of the acceleration does not have to be the same as the direction of the velocity. The units for acceleration are meters per second squared (m/s2). a = acceleration (m/s2)
