Calculate the acceleration in meters per second-squared, of a car that begins at rest at a stop sign and accelerates to 25 m/s over a time of 8.6 seconds.

vf = vi +  a t          

vi = initial velocity  (zero in this case....it starts at rest)      vf = final velocity   (25 m/s)      t = time (8.6 s)
