Maybe she needs to slow down to half speed to hit the button? Assuming constant and same acceleration and deceleration that is the same number of seconds for the start and each of the 23 buttons, additionally assuming a flying finish, that is 24 times the time to full speed spent accelerating and decelerating. At 2 seconds to full speed that is only 48 seconds of the total 300 averaging half speed, resulting in 326 km/h required full speed. 3 seconds acc/dec is 72 seconds half speed, requires 341 km/h full speed. Which is a whole lot more than 285 km/h.

My conclusion: Nadine can hit the buttons while going more than half speed. Probably not at full speed, but likely at 200 km/h or so. (And I should be exercising my newRPL 50g a lot more often.)

]]>Time to make some assumptions! I’m going to assume that her acceleration is constant, and her deceleration is the same (it makes the maths so much easier) and run through a few possibilities:

1: She needs to stop to hit each button and is spending her entire run accelerating and decelerating (reaching top speed in 6 seconds and immediately slowing down to hit the next button). Required max speed: 600KpS.

2: She needs to stop to hit each button, but only needs 1 second to reach the run’s top speed (and 1 second to stop). Required max speed: 327.272727â€¦KpS

3: She can it the buttons without slowing and needs 6 seconds to reach top speed (and to stop at the end – again, it makes the maths easier). Required max speed: 306.122449KpS

4: She can hit the buttons without slowing and only needs 1 second to reach top speed: Required max speed: 301.003344KpS

All in all, acceleration time plays a far smaller role in her speed requirements than I expected (exept the first scenario – that one I didn’t need the calculator for). Interestingly, I did a little bit of reserch and found that the limiting factors on human speed (assuming the speed of your limbs isn’t the problem) are traction (which can be improved by going barefoot so you can grab the ground with your toes, or crawling) and your knees hitting the ground as you lean into the wind (which can be avoided by running backwards, or crawling)â€¦ I suspect actual speedsters would look rather weird going from A to Bâ€¦ ]]>
