I have a hard one here :(adsbygoogle = window.adsbygoogle || []).push({});

The lane for starting a airplane must be long enough for a airplane to accelerate to 300km/h with a constant acceleration on 1.6m/s2. How long must the startlane be?

This is what I've found out,

I take 300km/h and make it to m/s

300 / 3.6 = 83,3m/s

Then I because I don't know the time I take

t=v/a 83,3/1,6=132,8sek

Then I take

S=1/2(v0+v)*t = 1/2(0+83)*132,8 = 5511m = 5,5km

But I think that's not the right answer what have I done wrong?

Thankful for all help
