a bus traveling in a straight line with uniform acceleration has an instant speed of 6m/s. 5seconds later, has reached speed of 36m/s. Find the magnitude of its acceleration and the distance traveled in 5seconds

A rough value of deceleration of a skidding automobile is about 7.0m/s. Using this how long does it take for a car going at 30m/s to stop after the skid starts. How far does the car go in this time.
