At t=0 s, a car cruises at a constant positive velocity. Suddenly, a light switches to red. At t=$maxbraketime s, the driver is maximum on the brake. The car then stops in front of the red light for over $wait seconds. Eventually, it drives off, and then again cruises at a constant velocity. The car cannot accelerate with more than $maxacc m/s<sup>2</sup>.<br /> |
