Refer to the following information for the next eight questions.

An object, starting from rest, gains a speed v = at when it undergoes uniform acceleration. The distance it covers is d = ½at^{2}. Uniform acceleration occurs for a ball rolling down an inclined plane. The plane below is tilted so a ball picks up a speed of 2 m/s each second; then its acceleration a 2 m/s^{2}. The positions of the ball are shown for 1-second intervals. Fill in the blanks for total distance traveled, Δdistance traveled each second, and the final speed at the end of each interval.
