## Homework Statement

A crow flies in two successive displacements to a point that is 80 m to the west. Its first displacement is 80 m in a direction θ1 = 65° west of north.

a)What is the magnitude of its second displacement?

b)What is its direction of its second displacement measured by the angle θ2 measured west from north?

## Homework Equations

## The Attempt at a Solution

90-65= 25° N of W

cos25°= 80/c --> then c= 80/cos25°= 88.3m

c²=a²+b²

b=√(c²-a²)

b=√((88.3)²-(80)²)

b=37.4m

180°= 25°+90²+Θ

Θx=65°

360°-65°=

295° W of N
