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?
Solutions
Expert Solution
It seems to behorizantal prohection of the projectile.
Horizantal component of the velocity=V0 cos theta
=240*cos (-30)
=240* 
3/2
=207.846
-2400=240*sqrt(3)/2*t-(1/2)g t^2
-2400=207.85 t-0.5 t^2
-4800=415.69t-t^2
t^2-415.69t+4800=0
t=11.8869 sec
horizantal distance =Vocos theta*t= 2470.65 m
from the figure tan theta=2400/2470.65
theta =440 from the horizantal.(see figure)

An airplane flying in the air with a constant velocity of 240
m/s horizontally experiences a force due to gravity, directed
downwards with a magnitude of 4×10^6 N, and a force generated by
the engines, directed forwards with a magnitude of 3 × 10^6 N.
a. In light of Newton’s first law, why must there be a third
force acting on the airplane? Calculate the magnitude of this third
force, and explain its physical origin. Draw this third force on...

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.

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?

An airplane with a speed of 98.6 m/s is climbing upward at an
angle of 38.6 ° with respect to the horizontal. When the plane's
altitude is 671 m, the pilot releases a package. (a) Calculate the
distance along the ground, measured from a point directly beneath
the point of release, to where the package hits the earth. (b)
Relative to the ground, determine the angle of the velocity vector
of the package just before impact.
