# Mary and sally are in a foot race. When mary is 22 m from the finish line, she has a speed of 4.0 m/s and is 5.0 m behind Sally, who has a speed of 5.0 m/s. Sally thinks she has an easy win and so, during the remaining portion of the race, decelerates at a constant rate of 0.40 m/s^2 to the finish line. what constant acceleration does Mary now need during the remaining portion of the race, if she wishes to cross the finish line side-by-side with sally?
