Chapter 2, Problem 69PQ
A trooper is moving due south along the freeway at a speed of 21 m/s. At time t = 0, a red car passes the trooper. The red car moves with constant velocity of 28 m/s southward. At the instant the trooper’s car is passed, the trooper begins to speed up at a constant rate of 2.0 m/s2. What is the maximum distance ahead of the trooper that is reached by the red car?

A space shuttle is launched from rest. It takes 8.00 s to reach 158 km/h , and at the end of the first 1.00 min its speed is 1580 km/h .
Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 8.00 s to 1.00 min?
Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.0 km east of mile marker 0 traveling at 27.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.30 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.40 m/s2 .
At what time do the cars pass next to one another?
A blue car is moving at a constant speed of 70 m/s when it passes signage with a police officer beside it. Due to the car's over speeding, the police officer chases it with a constant acceleration of 4 m/s2, one second after the car passes the signage. How long does it the police officer to overtake the truck?
