The y component of a vector R of magnitude k = Bcm shown in the figure below is Ky = +6 cm. What is the direction of this vector (The angle 8 that makes K with the x axis)?

The y component of a vector R of magnitude k Bcm shown in the figure below is Ky 6 cm What is the direction of this vector The angle 8 that makes K with the x a class=

Respuesta :

Given

The y-component of vector K is

[tex]K_y=6\text{ cm}[/tex]

The magnitude of vector K is , K=8 cm

To find

The angle

[tex]\theta[/tex]

Explanation

Resolving K along its y-component we have,

[tex]\begin{gathered} K_y=Ksin\theta \\ \Rightarrow6=8sin\theta \\ \Rightarrow sin\theta=\frac{3}{4} \\ \Rightarrow\theta=48.59\text{ }^o \end{gathered}[/tex]

Conclusion

The angle made with the x-axis is

[tex]48.59^o[/tex]
