Question

An airplane originally at rest on a runway accelerates uniformly at 6.0 meters
per second2 for 12 seconds. During this 12-second intervai, the airplane
travels a distance of approximately

Answer 1

Under uniform acceleration starting a velocity v, a mass moves a distance, D, of

D = ut + 1/2 . at^2

here u = 0, t = 12 sec, a = 6 m/sec^2.
