I am stumped.
A car is driving North-West on the highway. It has a
speed of 20 m/s with the cruise control on.
Ten seconds later, the car is heading North-East (still going 20 m/s).
Determine a) the acceleration of the car.
b) The displacement of the car during the turn

I was able to find the average acceleration, but I could not find the displacement. 
We can't use the 4 kinematic equations because acceleration is not constant here.

you should think about posting the original question.

it seems that maybe the car is moving in a circle at constant speed?  *with cruise control*  is a hint
