Blown Duck
Posted on Thursday, December 11th, 2008 at 9:01 pmIn what direction should they head to go south?
A flock of ducks is trying to migrate south for the winter, but they continue to be won over by winds from the west at 6.0 m / s. A wise old duck finally realizes that the solution is flying at an angle to the wind. If ducks can fly at 8.0m / s relative to the air, what direction should they head to go south?
arcsin (8.6) = 48.6 ° S (No. 228.6 °) an additional credit W: Speed over ground 8cos48.6 = ° = 5.3 m / s
