Solve the all parts of given question:
Question: A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 12.0 m/s and accelerates at the rate of 0.650 m/s2 for 7.00 s.
Part A: What is his final velocity?
Part B: The racer continues at this velocity to the finish line. If he was 300 m from the finish line when he started to accelerate, how much time did he save?
Part C: One other racer was 5.00 m ahead when the winner started to accelerate, but he was unable to accelerate and traveled at 12.2 m/s until the finish line. How far ahead of him (in meters and in seconds) did the winner finish?
