I have a hard one here :
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
