Two cars cover the same distance in a straight line. Car A covers the distance at a constant velocity. Car B starts from rest, maintains a constant acceleration, and covers the distance in the same time as car A.
(a) Is car B's final velocity smaller than, equal to, or greater than car A's constant velocity?
(B) Is car B's average velocity smaller than, equal to, or greater than car A's constant velocity?
(c) Given a value for the time t to cover the distance and the fact that car B starts from rest, what other variable must be known before car B's acceleration can be determined?
1. its initial velocity 2. no other variables need to be known
3. its final velocity
