Question: 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.
1. A plane accelerates from rest at a constant rate of 5.00 along a runway that is 1800 long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time needed to take off?26.83s
2. What is the speed of the plane as it takes off? 134m/s
3. What is the distance traveled by the plane in the first second of its run?2.5m
4. What is the distance traveled by the plane in the last second before taking off?132m
5. What percentage of the takeoff velocity did the plane gain when it reached the midpoint of the runway? Express your answer numerically.
