Find x- and y-components of the vector \vec {v}=(2.0cm/s , - x-direction).
To find the x- and y-components of the vector, we first need to understand the given information.
The vector \vec{v} can be written as (2.0 cm/s, -x-direction). This means that the vector has a magnitude of 2.0 cm/s and is pointing in the negative x-direction.
The x-component of the vector represents the magnitude of the vector in the x-direction, while the y-component represents the magnitude in the y-direction. In this case, since the vector is pointing only in the x-direction, the y-component is zero.
Therefore, the x-component of the vector \vec{v} is 2.0 cm/s, and the y-component is 0.
