The phrase "I can only find the value of A-y-component" refers to a situation where a person is able to determine the value of the vertical component (y-component) of a vector A, but not the horizontal component (x-component).
Knowing both components of a vector is important because it allows for the accurate representation of the vector's direction and magnitude. Without both components, the vector cannot be fully described or used in calculations.
The value of the A-y-component can be found using trigonometric functions such as sine and cosine, or by using vector addition or subtraction with known components of other vectors.
If you only have the magnitude and direction of the vector, you can use trigonometry to calculate the components. The x-component can be found by multiplying the magnitude by the cosine of the direction angle, and the y-component can be found by multiplying the magnitude by the sine of the direction angle.
Yes, the A-y-component can be negative. This indicates that the vector is pointing downwards or in the negative direction on the y-axis. The negative sign is important for accurately representing the direction and magnitude of the vector.
