9) At an athletics meeting, competitors are running the 10,000 m. At the beginning of the last lap, the leader is exactly 350 m ahead of the runner in last place.
a) If the leader runs at the velocity of 4.2 m/s and the runner in last place runs at 3.6 m/s, will the leader lap the runner in last place?
b) When the leader is 100 m from the finish line, the runner in second place is 8 m behind. If the runner in second place is running at 4.2 m/s, and accelerates from that point at 0.15 m/s2 until he reaches the velocity of 4.8 m/s, who will win the race?
