Question

a particle has velocity 10m/s parallel to the x axis then its x and y components are?

Answer 1

X component is 10 m/s and Y component is is 0 m/s.

Given:

• Object has 10 m/s velocity parallel to x axis.

To find:

• X and Y Velocity component ?

Calculation:

Since the net velocity vector is parallel to the x-axis, we can say:

• The angle of the velocity vector with x axis is 0°
• Angle of velocity vector with y-axis is 90°

So, we can say:

$v_{x} = v \times \cos( {0}^{ \circ} )$

$\implies v_{x} = v \times 1$

$\implies v_{x} = v$

$\implies v_{x} = 10 \: m {s}^{ - 1}$

Again,

$v_{y} = v \times \cos( {90}^{ \circ} )$

$\implies v_{y} = v \times 0$

$\implies v_{y} = 0$

So, x component is 10 m/s and y component is 0 m/s.
