Question

An engineer is designing the run way for airport of the planes that will use the airport,the lowest acceleration rates is likely to be m/s. the take off speed for this plane will be 65m/s. Assuming this minimum acceleration, What is the minimum allowed length for the runway​

Answer 1

Answer:

The answer is 704 m

Explanation:

Given, initial velocity, u=0m/s and final velocity v=65m/s

Acceleration a=3m/s

2

If d be the allowed length for the runway.

Using formula v

−u

=2(3)d

⟹ d=65
