Answer:

Explanation:

This is a displacement vector since it is defined in terms of distance (meters, to be exact). The way you find the y-component is

[tex]V_y=Vsin\theta[/tex] which says that you multiply the magnitude of the vector (its length) by the sin of the direction (the angle):

[tex]V_y=12.2sin(81.5)[/tex] and get

[tex]V_y=[/tex]12.1 m
