A bee needs to fly to a flower 541 m due south
of its hive. The bee’s speed in still air is
0.67 m/s, and there is a wind blowing toward
the west at 0.2 m/s.
What is the magnitude of the bee’s resultant velocity?
Answer in units of m/s
Draw a velocity right triangle. The bee's direction (a bit east of south) is the hypotenuse.
In 1 second, the bee travels
√(.67^2 - .2^2) = 0.639 m due south
So the speed is 0.639 m/s
