solving deceleration problem using calculus?

This is very easy to do with physics equations but i have to do this using calculus. At a distance of 45m from a traffic light, a car travelling 15 m/sec is brought to a stop at a constant deceleration What is the value of deceleration? how far has the car moved when its speed has been reduced to 3 m/sec? How many seconds would the car take to come to a full stop?
