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 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?
