I can create/solve the math problem without any difficulties once I have diagram in place, but I am having trouble setting up the diagram so that I can visualize it. The questions is: A novice pilot sets a plane's controls, thinking the plane will fly at 2.50 x10^2 km/h to the north. If the wind blows at 75 km/h toward the southeast, what is the plane's resultant velocity. The diagram I have is starts with a vector going in a due north direction for 250km. At the top, I have the next vector going downward at a 45degree towards a SE direction. (see attached) My resultant vector then would be from the tail of the first vector to the tail of the southeasterly vector. While I can see what the answer SHOULD be...my diagram does not allow for the correct answer. Can someone please help me with what the diagram should look like and why? Thanks so much!!
