A force of 200N acts at an angle of 140° with respect to the positive x- direction. determine the components of this force in the x- and y- direction​

Respuesta :

Answer:

The components of the force in the x and y-direction are -153.21 N and 128.56 N respectively.

Explanation:

Rectangular components of a vector

Given a vector [tex]\vec F[/tex] as an ordered pair (f,θ), where f is the magnitude of the vector and θ is the angle it forms with the positive x-direction, the rectangular components of the vector are given by:

[tex]F_x=f.\cos\theta[/tex]

[tex]F_y=f.\sin\theta[/tex]

The force of f=200N forms an angle of θ=140°. The components of the force are:

[tex]F_x=200.\cos 140^\circ[/tex]

Calculating:

[tex]F_x=-153.21~N[/tex]

[tex]F_y=200.\sin 140^\circ[/tex]

[tex]F_y=128.56~N[/tex]

The components of the force in the x and y-direction are -153.21 N and 128.56 N respectively.
