Question

an aircraft is trying to fly due north at a speed of 100 m per sec. it is subjected to a cross wind blowing from west to east at speed of 50 m per sec what is the actual velocity of aircraft relative to surface of earth ​

Answer 1

Answer:

111.803 m/s

Explanation:

In the question,

Speed of flying of Aircraft due North, s₁ = 100 m/s

Speed of wind from West to East, s₂ = 50 m/s

Now,

We know that the relative sped of the aircraft w.r.t to Surface of Earth is given by,

$(s_{3})^{2} =(s_{1}) ^{2} +(s_{2} )^{2}\\s_{3}=\sqrt{(s_{1}) ^{2} +(s_{2} )^{2}}  \\s_{3}=\sqrt{100 ^{2} +50^{2}}\\s_{3}=111.803m/s$

where,

s₃ is the resultant relative speed of the aircraft w.r.t the surface of Earth.

Hence, the correct answer is 111.803 m/s.
