Constants Part A Mary and Sally are in a foot race (see figure (Figure 1)). 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 0.46 m/s2 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? Express your answer using two significant figures. View Available Hint(s) 2 m/s Submit Figure 1 of 1 Provide Feedback Next > Finish Mary Sally 4.0 m/s5.0 m/s 5,0 m 22 m Pearson
