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 5.00m/s2along a runway that is 1800mlong. assume that the plane reaches the required takeoff velocity at the end of the runway. what is the timettoneeded to take off? express your answer in seconds using three significant figures.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
