At the end of a race a runner decelerates from a velocity of 8.70 m/s at a rate of 2.10 m/s². (a) How far in meters does she travel in the next 4.60 s? (Assume the deceleration of 2.10 m/s is constant over the full 4.60 s.) (b) What is her final velocity in m/s? (c) Evaluate the result. Does it make sense?
