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
