A car moving with a constant acceleration covers the distance between two points 80 m apart in 8.0 s. Its velocity as it passes the second point is 14 m/s.
(a) What was the speed at the first point?
1 m/s
(b) What is the constant acceleration?
2 m/s2
(c) How far behind the first point was the car at rest?
3 m
