Asked by Alex
A plane leaves Toronto and flies with an airspeed of 2.20 x 10^2 km/h always pointing due east. A wind is blowing from the north at 8.0 x 10^1 km/h.
a) What is the plane's velocity relative to the ground?
b) What is the plane's displacement from Toronto after flying for 2.5h?

For (a), draw and solve a vector diagram.
Air velocity + Airspeed vector = Ground speed vector
For (b) Multiply the Ground speed vector by 2 hours, and the answer will be the displacement vector.
I will be glad to critique your work.

a) I did the pythagorean theorem and got 234 km/h. I did Tan O = O/A and got [E20N] for my direction.
b) I got 585 km.
Did I get the right answers? I was a bit confused by part a because I thought it also involved gravity.
