Mary and Sally are in a foot race (see the figure). 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 0.36 m/s2 to the finish line.
What constant acceleration does Mary now need during the

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 0.49 m/s2 to the finish line.

Sally and David are runners participating in a relay race. Sally runs at a constant speed of 2.0 m/s. When she is 1.8 m behind David, he starts from rest and begins to run in the same direction as Sally with a constant acceleration of 0.5 m/s^2. When Sally reaches him, she hands him the baton. a) (20 points) How far has David run when he gets the baton? b) (5 points) What is David’s speed at the moment he...

Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.45 m/s, and the second a velocity of 4.25 m/s. (a) What is the velocity(in m/s) of the second runner relative to the first? m/s faster than the front runner (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity O...
