Question

An aeroplane starts from rest with an acceleration of 3 m/s2 and takes a run for 35 s before taking off. what is the minimum length of runway and with what velocity the plane took off?

Answer 1

acceleration = 3m / second ^2
V= ?
U = 0
S = ut + 1/ 2 at^2
S = 0 × 35 +1/2 3 × 35^ 2
S= 1/2 × 3 × 1125
S = 1126.5
So the length of the runway = 1126.5

Answer 2

Answer:

runway lenght =1125m

v=105m/s^2
