Review Conceptual Example 6 as background for this problem.
14.
A car is traveling to the left, which is the negative direction. The direction of travel remains the same throughout this
problem. The car's initial speed is 27.0 m/s, and during a 5.0-s interval, it changes to a final speed of (a) 29.0 m/s and (b)
23.0 m/s. In each case, find the acceleration (magnitude and algebraic sign) and state whether or not the car is
decelerating.
