Upper?
plane
... N component ... 450 kph cos(45º)
... E component ... 450 kph sin(45º)
wind
... N component ... 60 kph cos(30º)
... W component ... 60 kph sin(30º)
add the components to find the resultant vector
An airplane has an airspeed of 450 kilometers per hour bearing Upper N45E. The wind velocity is 60 kilometers per hour in the direction Upper N30W. Find the resultant vector representing the path of the plane relative to the ground. What is the ground speed of the plane? What is its direction?
