A car starts from rest and travels for 5s with a uniform acceleration of +1.5 m/s2. The driver then applies the brakes, causing a uniform acceleration of –2 m/s2. If the brakes are applied for 3 s, (a) how fast is the car going at the end of the braking period, and (b) how far has the car gone?

A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
A train is traveling down a straight track at 20 m/s when the engineer applies the brakes, resulting in an acceleration of −1.0 m/s2 as long as the train is in motion. How far does the train move during a 40-s time interval starting at the instant the brakes are applied?
A car starts from rest, then accelerates at a constant rate over a distance of 96 m. It then immediately decelerates at a constant rate over a distance of 178 m.
