What is the y component of a vector defined as 12.2m at 81.5°? 12.1m

1.80m

-1.80m

-12.1m

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

which says that you multiply the magnitude of the vector (its length) by the sin of the direction (the angle):

and get

12.1 m
