Think about what Acceleration is.

Isn't it the Change in Velocity over time? In this case it is the change in the Velocity vector divided by time. You have the final Velocity vector of 14 East and you subtract the initial Velocity vector 14 South. The negative of the initial is 14 North, so your vector addition should be adding together the 14 East Vector with a 14 North vector. You find the magnitude (and divide by the time of course) as you did in part c) and direction as you did in part d)
