Q. A driver traveling at 44.0 km/h in a school zone can brake to an emergency stop in 2.80 m. What would be the braking distance if the car were traveling at 52.0 km/h?

Q. Two trains face each other on adjacent tracks. They are initially at rest, and their front ends are 35 m apart. The train on the left accelerates rightward at 0.91 m/s2. The train on the right accelerates leftward at 0.82 m/s2.How far does the train on the left travel before the front ends of the trains pass?
