Question

An engineer is designing the runway for a new airport. The lowest

acceleration rate of the plane's that will use the airport is likely to
be 3.0 m/s2. The takeoff speed for that plane is 65 m/s. What is
the minimum runway length needed for this plane to successfully
takeoff?

Answer 1

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

=2(3)d

⟹ d=65
