An airplane travels 600 m down the runway before taking off. If it starts from rest, moves with constant acceleration, and becomes airborne in 15.0s, what is its speed in m/s^-1, when it takes off?
A jet with mass m = 1.4 × 105 kg jet accelerates down the runway for takeoff at 1.7 m/s2. 1) What is the net horizontal force on the airplane as it accelerates for takeoff? 2) What is the net vertical force on the airplane as it accelerates for takeoff? 3) Once off the ground, the plane climbs upward for 20 seconds. During this time, the vertical speed increases from zero to 26 m/s, while the horizontal speed increases from...
An airplane accelerates down a run-way at 3.20 m/s2 for 32.8 s until it finally lifts off the ground. Determine the distance traveled before take-off. What is the plane’s velocity at takeoff (32.8s)?
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...
A jet with mass m = 6 × 104 kg jet accelerates down the runway for takeoff at 2 m/s2. 5) After reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 17 seconds. What is the net horizontal force on the airplane as it levels off? 6) What is the net vertical force on the airplane as it levels off?
An airplane needs to reach a velocity of 32.0m/s before it can take off. If it accelerates at a rate of 1.52m/s2, how long must the runway be? Assume that the plane starts from a stationary position at the bottom of the runway
A speedboat starts from rest and accelerates at +2.01 m/s2 for 7.50 s. At the end of this time, the boat continues for an additional 5.75 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at −1.49 m/s2 for 8.35 s.
An airplane starts from rest on the runway. The engines exert a constant force of 78.0 kN on the body of the plane (mass 9.20 × 104 kg) during takeoff. How far down the runway does the plane reach its takeoff speed of 74.7 m/s?
A speedboat starts from rest and accelerates at m/s2 for s. At the end of this time, the boat continues for an additional s with acceleration m/s2. Following this, the boat accelerates at m/s2 for s.
