Homework Help: physics

Posted by Karen on Sunday, September 8, 2013 at 4:23pm.

A Boeing 787 is initially moving down the runway at 3.0 m/s preparing for takeoff. The pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.7 m/s2. The plane then travels a distance of 1900 m down the runway before lifting off. How long does it take from the application of the acceleration until the plane lifts off, becoming airborne?
