A block of wood of mass 6.0 kg slides along a skating rink at 12.5 m/s^2 [w] . The block slides onto a rough section of ice that exerts a force of 30 N force of friction on the block of wood. The acceleration of the block of wood is 5.0 m/s^2 [E] and it takes 2.5s to stop. How far does the block slide after friction begins to act on it ?

12.5 m/s^2 is not a speed. It is an acceleration rate.
What are the [w] and [E] supposed to mean?
Your 5.0 m/s^2 "acceleration" rate should be negative if the block is stopping.
