Homework Statement
Snoopy is flying his plane, the Sopwith Camel, in search of the Red Baron. He flies with a constant speed of 120 km/h relative to air, and makes instantaneous turns when necessary. He follows a perfectly square path on the ground, using north - south and east - west roads as a guide for each of the 60 km sides. On a day when there is a steady 60 km/h wind blowing diagonally across the square (southwest wind), how long does the trip take?
Homework Equations
Relative Motion
V-speed, P-Plane, A-Air, G-Ground
PVG = PVA + AVG
Cosine Law
The Attempt at a Solution
My assumption on the problem is that the airspeed of 120 km/h must have an added components of 60 km/h (NE) to counteract it so that the resultant will have its course on the correct path 60 km North. This is done for each side.
I have drawn out my vectors in the attached image.
Using cosine law I can find the new airspeed, but I don't know what to do after.
Please Help and Thank You
