Please show your work. How did you calculate the acceleration?

V(final)= Displacemenet/Time << to get the time
then
Acceleration= V(final)/Time

but am not sure ...

To get the time you'll need the average velocity, not the final velocity.

then
Acceleration= V(final)/Time

Acceleration = ΔV/Time.
