world-champion sprinter runs the 100-meter dash. He accelerates from rest at a rate of 2.4 m/s for the first 50 meters, and then maintains a constant speed for the remainder of the race, a.) What are the sprinter's times for the first 50 meters and for the entire race? b.) Draw a graph of the sprinter's velocity versus time for the entire race. (Be sure to use the correct numbers and scale on the axes.)
