A worker pushes a crate horizontally across a warehouse floor with a force of 245 N at an angle of 55 degrees below the horizontal. How much of the worker’s force is not used to move the crate?

Respuesta :

Answer:

200.66 N

Explanation:

We are given that

Force,F=245 N

[tex]\theta=55^{\circ}[/tex]

We have to find  the force of worker is not used to move the crate.

Force along x- axis=[tex]Fcos\theta=245cos55^{\circ}[/tex]

It acts in the direction of displacement.Therefore, it is used to move the crate.

Force along y- axis=[tex]Fsin\theta=245sin55=200.66 N[/tex]

It is not used to move the crate.

Hence,the worker's force  which is not used to move the crate=200.66 N
