1. ### What happens when an airplane gets too high?

As you get higher the air gets thinner, which means you need more speed to get lift. But since the air is thinner there is also decreasing oxygen, which means at some point the plane just plateaus because the air doesn't have...

4. ### A jet with mass m = 6 × 104 kg jet accelerates down the runway for takeoff at 2m/s^2?

1) Given the take-off acceleration is 2 m/s^2, let the Vertical & Horizontal components of acceleration are equal i.e. aX = aY = 2 m/s^2, =>By Fx = m x aX =>Fx = 6 x 10^4 x 2 =>Fx = 12 x 10^4 N 2...

5. ### You are traveling on an airplane . The velocity of the plane with respect to the air is 110 m/s due east.?

Vp = velocity of plane = 110 m/s Vp(x) = x-component of plane's velocity = 110 m/s Vp(y) = y-component of plane's velocity = 0 m/s θp(com) = compass direction of plane = 90 ° θp(xy) = direction of plane on x-y axes = 0 ° Va = velocity of air = 41 m/s Va(x) = x-component of air's velocity = to be...

7. ### An airplane takes off at a 50° angle from the ground. It ascends a distance of 12 km. How high above the ground is the plane at this-?

Well, if it ascends a distance of 12 km, then it is 12 km above the ground. But if traveled a distance of 12 km at an angle of 50º above the horizontal, then it ascended y = 12km * sin50º = 9.2 km and I'm pretty sure that's what you're...

9. ### Does RPM vary linearly with the speed of an airplane ?

It depends how accurate you are trying to be.  Let’s assume the model only has to deal with a horizontal flight-path. (Which is very inaccurate model.) The drag force (D) is approximately proportional to v².  So D...
