Daniel is nearing the end of a 100k bike race. He has a velocity of 11.5 m/s, gives it his all, and accelerates at 0.500 /^2 for 7.00 s.
a. What is Daniel’s final velocity?
b. Daniel continues at this new velocity to the finish line. If he is 300 m from the finish line
when he starts to accelerate, how much time did he save compared to if he didn’t
accelerate?
c. The second-place winner, Scott, was 5.00 m ahead when Daniel started to accelerate, but
he was unable to accelerate, and traveled at 11.8 m/s until the finish line. What was the
difference in finish time between Daniel and Scott?
d. How far back was Scott when Daniel crossed the finish line?
