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?
Question 16
1.
A ship is 1200 m from shore and is using a searchlight to scan
the shoreline.
The search light is being rotated at a constant angular speed
of
d(th)/dt = 0.25 rad/sec.
Find the rate at which the light is moving along the shore at
the time when the light is 500 m down the shore from the straight
line distance to the boat.

A plane flying with a constant speed of 19 km/min passes over a
ground radar station at an altitude of 14 km and climbs at an angle
of 20 degrees. At what rate is the distance from the plane to the
radar station increasing 4 minutes later?
The distance is increasing at km/min.

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~!

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.

As an airplane is taking off at an airport its position is
closely monitored by radar. The following three positions are
measured with their corresponding times:
x1 = 264.08 m at t1 = 4.90 s,
x2 = 312.33 m at t2 = 5.40 s,
x3 = 364.72 m at t3 = 5.90 s.
What is the acceleration of the airplane at t2 = 5.40 s?
(Assume that the acceleration of the airplane is constant.)
a=_______m/s^2

8. Consider an airplane whose takeoff speed is 220 km/h and that
takes 15 s to take off at sea level. For an airport at an elevation
of 1600 m (such as Denver), determine (a) the takeoff speed, (b)
the takeoff time, and (c) the addition al runway length required
for this airplane. Assume constant acceleration for both cases.

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.

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...
