The distance traveled is dependent on the initial velocity, the acceleration and the time of travel. An object, initially moving at 29 m/s, is accelerated at 8 m/s2 for 9 seconds, what distance does it travel in the 9 second time interval? What is the objects speed at the end of 9 seconds? What is the average velocity for the object? What is the distance traveled during the last second?
