Homework Statement
An airliner is flying in the direction North 20 degrees East with an airspeed of 300mph. Its ground speed and true course are 350mph and 30 degrees respectively(RESULTANT). Use a vector analysis to determine the direction and speed of the wind. Include a diagram.
Homework Equations
The Attempt at a Solution
350mph/30 is the resultant/true course
I setup x components and y components to add below:
x:
300cos(70)+wind[cos(theta)]
y:
and 300sin(70)+wind[sin(theta)]
I don't know how to substitute properly to solve for the two variables theta and wind - which is the mph speed of the wind which is the second vector and not the resultant. Please help this is due tomorrow morning.
