A toy airplane is flying in a straight horizontal (parallel to the ground) path with a speed of vi = 34.0 m/s. Suddenly, the airplane's engines stop (at t=0). Using an x-axis that is horizontal and along the plane's original velocity and a y-axis that is vertical with positive away from the ground, the airplane now has an acceleration given by the following expressions:

ax(t) = − t2/C
ay(t) = − g [ 1 − vx(t)/vi ]

where C = 2680 s4/m and vx(t) is the x component of the airplane's velocity. The airplane crashes 40.45 seconds after the engines stop.

What is the vertical component of the airplane's velocity vy at the instant of the crash?
What is the airplane's impact speed when it crashes?
How high up was the airplane before its engines stopped?
How far did the airplane travel in the x direction from the time when its engines stopped to the time it crashed?

An airplane is flying at a constant horizontal velocity of 184.5 m/s and drops a rocket. The rocket falls for 10.24 s without air resistance and under the influence of gravity only, and then fires its thrusters. From the moment the thrusters are one, the rocket has a net acceleration of 5.481 direscted 30.21 degrees above the horizontal. How far apart are the plane and the rocket when the rocket passes back through the cruising altitude of the plane?

question 15 Speed of airplane flying overhead of radar station An airplane is flying at an altitude of 6 miles and passes directly over a radar antenna. When the plane is 10 miles away (straight line distance from radar station s=10), the radar detects that the distance s is changing at a rate of 320 mph. What is the actual speed of the plane?

Two airplanes are flying in the air at the same height. Airplane A is flying east at 250 mph and airplane B is flying north at 400 mph. If they are both heading to the same airport, located 30 miles east of airplane A and 40 miles north of airplane B, at what rate (in mph) is the distance between the airplanes changing?

An airplane is flying with a velocity of v0 at an angle of α above the horizontal. When the plane is a distance h directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance. Take the free fall acceleration to be g.

1) An airplane is flying through a thundercloud at a height of 2000 m. (This is very dangerous because of updrafts, turbulence, and the possibility of electric discharge.) If there are charge concentrations of 45 C at height 3300 m within the cloud and −41 C at height 948 m, what is the strength of the electric field E at the aircraft? The Coulomb constant is 8.99 × 109 N·m2 /C 2 . Answer in units of V/m. 2) Find...

If you were flying a model airplane on a wire so that it traveled in a circle around you, would you hear a Doppler shift in the sound from the airplane? Explain. In Olympic sprint events, the sound of the starter gun is sent to individual speakers at each runner’s starting block rather than relying on the sound traveling through the air. Why? Does the speed of sound waves through air depend on the frequency of the sound? Justify or...
