Question

Two cars are travelling towards each other on a straight road with velocities $10 m s^{- 1}$ and $12 m s^{- 1}$ respectively. When they are 150 m apart, both drivers apply their brakes and each car decelerates $10 m s^{- 1}$ until it stops. How far apart will they be when they have come to rest?

On a foggy day, two car drivers spot each other, when they are just 80 m apart. They are traveling at 72 km/h and 60 km/h respectively towards each other. Both of them simultaneously apply brakes, which retard both the cars at a rate of 5 m/s². Determine whether they avert the collision or not.
