Answer:
The velocity 2 m/s will be positive along positive direction and it will be negative along negative direction.
B is correct.
Explanation:
Given that,
Velocity v = 4.0 m/s
Angle [tex]\theta = 60^{\circ}[/tex]
An object travels with velocity v = 4.0 meters/second and it makes an angle of 60.0° with the positive direction of the y-axis.
According to figure,
The component of given velocity
[tex]v_{x}= v\ cos\theta[/tex]
[tex]v_{y}= v\ sin\theta[/tex]
The possible value of [tex]v_{x}[/tex] will be
[tex]v_{x}= v\ cos\theta[/tex]
[tex]v_{x}=4\times\ cos60^{\circ}[/tex]
[tex]v_{x}=4\times\dfrac{1}{2}[/tex]
[tex]v_{x}=2\ m/s[/tex]
The possible value of [tex]v_{x}[/tex] will be 2 m/s.
Hence, The velocity 2 m/s will be positive along positive direction and it will be negative along negative direction.
