Chapter 2, Problem 69GP
A car starts from rest at a stop sign. It accelerates at 2.0 m/s2 for 6.0 seconds, coasts for 2.0 s, and then slows down at a rate of 1.5 m/s2 for the next stop sign. How far apart are the stop signs?

A mountain biker cycling a trail traveling at 5.4 m/s begins to slow down when she notices a wooden bridge ahead has flooded. If she begins braking when she is 15.0 m from the bridge and comes to a stop just before reaching the bridge, how long did it take her to stop?
Just as a car starts to accelerate from rest with acceleration 1.4 m/s2, a bus moving with a constant speed of 12 m/s passes it in a parallel lane. How long before the car overtakes the bus? How fast will the car then be going? How far will the car then have gone?
