Question

A bird flies 3.0 km due west and then 2.0 km due north. Another bird flies 2.0 km due west and 3.0 km due north. What is the angle between the net displacement vectors for the two birds?

Answer 1

The answer is 22.62 degrees

Explanation:

First we need to find the angle between west direction and vectors given.

The angle between west direction and vector 1 is arctan(2/3)=33.69

The angle between west direction and vector 2 is arctan(3/2)=56.31

Angle between vector 2 and vector 1 is 56.31-33.69=22.62 degrees
