Question

The portion of the total or resultant vector acting in the horizontal direction.

Answer 1

Horizontal component

Step-by-step explanation:

Answer 2

Horizontal component,
`v_x = v cos \theta`

Step-by-step explanation:

A vector can be resolved along two perpendicular directions, which are usually chosen as the horizontal (x) and vertical (y) direction of the cartesian plane.

Calling v the resultant vector, the horizontal component is written as

`v_x = v cos \theta`

where

v is the magnitude of the resultant vector

`\theta` is the angle between the direction of the resultant vector and the positive x-direction

While the vertical component is given by

`v_y = v sin \theta`
