To take off from the ground, an airplane must reach a sufficiently high speed. the velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity.
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 t to needed to take off? express your answer in seconds using three significant figures.
