A ball rolls onto the path of your car as you drive down a quiet neighborhood street. To avoid hitting the child that runs to retrieve the ball, you apply your brakes for 1.06 s. The car slows down from 14.5î + 4.50
How far did the car move while braking?

NOTE: I already solved the first question (a) in the picture. I'm stuck on (b).
(vi +vf)/2 = D/t
The Attempt at a Solution
[([ (14.5i + 8.25k) + (4.50i + 3.50k) ] * 1.06)] / 2 = 12.0575i + 4.24k.
After applying the Pythagorean theorem, my result was 12.78 meters. That answer was rejected.
