Answer #1

Initial velocity of the plane = V1 = 0 m/s

Final velocity of the plane = V2

Acceleration of the plane = a = 3.2 m/s2

Time period the plane accelerates for = T = 32.8 sec

V2 = V1 + aT

V2 = 0 + (3.2)(32.8)

V2 = 104.96 m/s

Velocity of the plane at takeoff = 104.96 m/s

    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 5.00m/s2 along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tTO needed to take off?...

    An Airbus A310 is initially moving down the runway at 7.0 m/s preparing for takeoff. The pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.8 m/s2. The plane then travels a distance of 1500 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?

    A jet with mass m = 8 × 104 kg jet accelerates down the runway for takeoff at 1.5 m/s2. Once off the ground, the plane climbs upward for 20 seconds. During this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 96 m/s. After reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 11 seconds.What is the...
