A spinter in 100 m race, covers 4m in first section 30m in next y sec 52 m in another 4 sec and finishes the race 10 sec. Then find : 1) Average velocity of a spinter
2)What is the peak velocity attend the
spinter
3)During which time interval is the e
laccelerating highest ?

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Your answer is 120miles
