Question

an air craft has a takeoff velocity of 180km/h. what length of runway is needed? the accelaration of aircraft along the runway is 2.5 m/s^2

Answer 1

v^2 = 2as
convert km/h to m/s and plug in the numbers to find s.

Answer 2

2505

Answer 3

V^2=2as.
Convert 180km/hr into m/s.
180000/3600=50m/s.
Then put in-
v^2=2as

(50)^2=2*(2.5m/s)^2*s
2500=5*s
s=500m
