Acessna aircraft has a liftoff speed of v = km/h = 33.3 m/s.
a) what minimum constant acceleration does the aircraft require if it is to be airborne after a takeoff run of s = 240 m?
b) how long does it take the aircraft to become airborne?

a) Minimum acceleration is .

b) It will take .

Explanation:

Let's order the information.

Initial velocity:

Final velocity:

Initial position:

Final position:

a) We can use velocity's equation:

⇒

⇒ .

b) For this, equation for average acceleration will be helpful. Taking and having as the unknown time it becomes airborne:

⇒

⇒ .

this is a good question! i'll do some research and come back when i have the answer!

e/c, where e is its total energy
