Question

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

12.1m

1.80m

-1.80m

-12.1m

Answer 1

Step-by-step 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

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

`V_y=12.2sin(81.5)` and get

`V_y=`12.1 m
