An airplane pilot wishes to fly due west. a wind of 80.0 km> h (about 50 mi > h ) is blowing toward the south. (a) if the airspeed of the plane (its speed in still air) is 320.0 km> h (about 200 mi> h ), in which direction should the pilot head?

let the plane is flying at some angle theta with west towards north

Now we can use the components

now since plane has to fly towards west so net speed in north must be equal to speed in south for air

So we can say

so plane has to fly in direction 14.5 degree North of west

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

true tan speed = ang vel x radius
