Can you show the formula for how you found the answer and explain how to do it.

**drwls**, Tuesday, February 5, 2008 at 7:27pmThe velocity achieved after going a distance X while accelerating at a rate a, from a standing start, is

V = sqrt (2 a X)

Rearrange that equaiton to arrive at the acceleration "a" needed to achieve velocity V at runway distance X:

2aX = V^2

a = V^2/(2X)

Thanks
