The minimum takeoff speed for a certain airplane is 75 m/s. What minimum acceleration is required if the plane must leave a runway of length 1050 m? Assume the plane starts from rest at one end of the runway.

Given :

Initial Velocity,  u = 0

Final Velocity,  v = 75 m/s

Distance, s = 1050 m

Acceleration,  a = ?

v² - u² = 2as

(75)² -(0)² = 2a(1050)

5625 = 2100a

a = 5625/2100

a = 2.67 m/s²

 

Thus, the required Acceleration is 2.67 m/s².
