Some of the fastest dragsters (called "top fuel) do not race for more than 300-400m for safety reasons. Consider such a dragster

in this problem, starting a race at rest. After the light turns green, the dragster completes a 400 m race in a time t = 8.6 5.

Answer:

1.10261 times the acceleration due to gravity

416.17506 mph

Explanation:

t = duration

u = initial speed

v = speed at end

s = distance moved

a = acceleration

g = gravity acceleration = 9.81 m/s²

$s=ut+\frac{1}{2}at^2\\\Rightarrow 400=0\times 8.6+\frac{1}{2}\times a\times 8.6^2\\\Rightarrow a=\frac{400\times 2}{8.6^2}\\\Rightarrow a=10.81665\ m/s^2$
