V 0 = 0, v to = v 0 + a t = a t
x = a t² /2
2500 = 1.3 t² / 2
1.3 t² = 5000
t² = 5000 : 1.3 = 3,846.15
t = √ 3,846.15 ≈ 62 s
v to = 1.3 m/s² · 62 s = 80.625 m / s > 75 m/s ( takeoff speed )
Yes, the plane will be able to use this runway safely.

690

Step-by-step explanation:

So, you should do

46,000 * 9% = 4,140

4,140 divided by 6 = 690

So your answer is 690
