Wen taking off, an arcraft accelerates from 0 to 100 m/s in a distance of 500m.?

Question

how long did it take to travel this distance?

answer= 10s

Answer 1

10 seconds.

Answer 2

Vf^2-Vi^2/2d=a

10,000-0/1000=a

10 m/s^2=a

d=Vit+at^2/2

Vi=0 so we can remove it

500=(10t^2/2)

1000=10t^2

100=t^2

10 seconds=t

Answer 3

Yeah.

x - xi = 1/2(vi + v)t

2(x - xi) / (vi + v) = t

2(500m - 0m) / (0 + 100m/s) = t

(1,000m) / (100m/s) = t

t = 10s
