Vaug (equation 2 magnitude only) (vaug) (1.11)x (3.396) rvaus) 3.774 m/sExplanation / Answer
1.Vavg = SL x SR
SL increases from 0.769 m/steps uptil 2m/step in Fast mode which is also max.
Increase of SL from Very Slow to Slow is 0.342 m/step and from Slow to medium is 0.427 m/step, until it reaches peak at 2m /step with increase from medium to Fast by 0.462 m/step and remain constant at this level.
SR increase from very slow to Slow and come down from slow to medium until Fast and then again suddenly increase towards peak in the last lap with max rate at 3.484 steps/sec.
2. Average velocity in 1st part is 5m/sec while in the next 10 mt it is 7.14 m/sec due to acceleration in velocity of 1.53m/sec2. As the avrage velocity is continuously increasing due to acceleration and so for every time steps Average velocity will go up.
3. Average acceleration is continously increasing and so it will not be the same from intial 5 m step to the final 5 m step. But once it reaches to the pick at the end of slow step, it remain constant at 0.3 m/s2 to 0.35m/s2 until it reaches to the maxium.
4.As the sprinter will apply its maximum power and so beyond a limit which he has achieved in Fast stage, he will not be further able to accelerate. Further, within increasing rate of acceleration, velocity goes up and also air resistance also increase which lead to no further addition in acceleration as it is equally opposed by drag force and thus increase in acceleration stops and even slightly decerease as velocity keep on increasing with elapsed time.
