Use the worked example above to help you solve this problem. A typical jetliner lands at a speed of 154 mi/h and decelerates at the rate of (10.5 mi/h)/s. If the jetliner travels at a constant speed of 154 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
