1. If you were flying a model airplane on a wire so that it traveled in a circle around you, would you heara Doppler shift in the sound from the airplane? Explain.
2. In Olympic sprint events, the sound of the starter gun is sent to individual speakers at each runner’sstarting block rather than relying on the sound traveling through the air. Why?
3. Does the speed of sound waves through air depend on the frequency of the sound? Justify or illustrateyour answer.
4. Explainin your own wordswhat resonance is.
5. Draw a fifth harmonic standing wave on a string with fixed ends. (You may include a photo of yourdrawing in your submission on Canvas or turn it in on paper in class, but it should be your own drawing.)a. If the length of the string is 100 cm, what is the wavelength of the fifth harmonic? Of the firstharmonic? Explain.b. If the frequency of the fifth harmonic is 400 Hz, what is the frequency of the first harmonic? Explain.

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?

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.

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.

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 =...

An airplane is flying with a velocity of 240 m/s at an angle of
30.0° with the horizontal, as the drawing shows. When the altitude
of the plane is 2.4 km, a flare is released from the plane. The
flare hits the target on the ground. What is the angle
θ?

An airplane is flying at an air speed of 420 km/h on a heading
of 210o. A 45 km/h wind is blowing from a bearing of
50o. Determine the bearing and ground velocity of the
airplane using geometric vectors.
Please include what equation we are trying to solve for, thank
you in advance~!
