Question
An object is traveling eastward at a speed of 500 ms-1 flies into a 90ms-1 crosswind blowing southward.
a) calculate the resultant velocity of the plane relative to the object as it flies through the crosswind.
b) A person is steering the object, calculate the direction the person would have to steer in order for the resultant velocity off the plane to remain eastward.
My attempt
a) Magnitude of R=squareroot(902+5002)
= 508ms-1
Direction= tan-1(90/500) = 10.2
90-10.2= 79.8
Resultant= 508ms-1 at 79.8 degrees to the ground
b) don't know what to do, would you please be able to help me on this one? I don't really understand what it wants me to do
Thanks for any help you can give
