A Cessna aircraft has a lift off speed of 147 km/h. What minimum constant acceleration does this require if the aircraft is to be airborne after a take off run of 208 m?

The acceleration is  

Explanation:

From the question we are told that

   The lift up speed is  

    The distance covered for the take off run is

Generally from kinematic equation we have that

Here u is the initial  speed of the aircraft with value 0 m/ s give that the aircraft started from rest

So
