An airplane has a velocity relative to the ground of 203 m/s toward the east. The pilot measures his airspeed (the speed of the plane relative to the air) to be 111 m/s. What is the minimum wind velocity possible? Give you answer as a positive value.

Respuesta :

Answer:

92 m/s

Explanation:

The speed of Airplane when observed from the ground is 203 m/s i.e., speed of Airplane when there is no wind = [tex]v_a[/tex]

The speed of the airplane relative to the air is 111 m/s = [tex]v_r[/tex]

This means that the airplane is moving against the current

Speed of the current with respect to the ground = [tex]v_c[/tex]

[tex]v_a-v_c=v_r\\\Rightarrow 203-v_c=111\\\Rightarrow v_c=203-111\\\Rightarrow v_c=92\ m/s[/tex]

Velocity of current has to be atleast 92 m/s
