Question

A small airplane flies at 60 m/s relative to the air. The wind is blowing at 20 m/s to the south. The pilot heads this plane east. a) What is the speed, v, that the plane will travel relative to the ground

Answer 1

`V_g=63.3m/s`

Step-by-step explanation:

From the question we are told that:

Speed of Plane
`v_s=60m/s`

Wind speed
`V_w=20m/s`

Generally the equation for Speed of plane relative to the ground V_g is mathematically given by

`V_g=√(V_s^2+V_w^2)`

`V_g=√(60^2+20^2)`

`V_g=√(4000)`

`V_g=63.3m/s`
