Sample Problem A drunk man was driving his car at a speed of 25.0 m/s (or 90 kph) when he saw a cow in the middle of the road, 50.0 m away from him. It took him 0.400 s to react at which the car was moving at constant speed. After that, he stepped on the brakes to stop at a rate of 6.00 m/. Is this acceleration enough to save him and the cow from an accident?

Sample Problem 1
A car, originally at 14. 00 m/s (about 50 kph) covered a distance of 250.0 m. If its
speed at the end of trip is 20.00 m/s (about 72 kph), how long did it take the car to cover
that distance?
Sample Problem 2
A car is speeding at a rate of 18.00 m/s (about 65 kph) when a dog suddenly
crosses the street. If it took 6.00 s for the car to stop, what acceleration did it achieve?
