Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.45 m/s, and the second a velocity of 4.25 m/s. (a) What is the velocity(in m/s) of the second runner relative to the first? m/s faster than the front runner (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity O...

A cyclist sprints at the end of a race to clinch a victory. She has an initial velocity of 11.3 m/s and accelerates at a rate of 0.610 m/s for 7.85 s. (a) What is her final velocity? (Enter the magnitude in m/s.) 16.089 m/s (b) The cyclist continues at this velocity to the finish line. If she is 300 m from the finish line when she starts to accelerate, how much time did she save (in s)? (c) The...

A runner is training for an upcoming race. In order to track the pace of the run, the runner is able to record time splits for the entire period. This allows the runner to produce the given velocity versus time graph. The run is broken into six segments. Assume the run is in a straight line.

Races in athletics are started by the sound of a starting gun, traditionally located to one side of the first lane. But are runners disadvantaged if they are further away from the person holding the starting gun? Task Using algebra, investigate whether the distance from the starting gun will impact on a runner’s ability to win a race. Explore which runners would be most disadvantaged if the race was won by 0.1 seconds or 0.01 seconds. Useful information Runners...
