A train travels along a straight piece of track between 2 stations A and B. The train starts from rest at A and accelerates at 1.25m/s2 until it reaches a speed of 20m/s. It then travels at this
speed for a distance of 1560m and then decelerates at 2m/s2 to come to rest at B. Find
(a) Distance from A to B
(b) Total time taken for the journey
(c) Average speed for the journey

What is the distance between (–2 1/2,-3) and (1, –3)?

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.
