A plane accelerates from rest at a constant rate of 5.00 m/s^2 along a runway that is 1800 m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time needed to take off?

Best ResponseYou've already chosen the best response.0I think you take 1800/5 to see how many 5m are in the 1800m which is 360 so it would take 360 (5m) to get to 1800 so s^2 = 360 square root both sides about 18.97 seconds... Not sure though

Best ResponseYou've already chosen the best response.0s = ut + (1/2)at^2 => 1800 = 0t + (5/2) t^2 => t^2 = 3600/5 =>t = sqrt(3600/5) = sqrt(720) = 12sqrt(5)
