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? (1 point)

Respuesta :

Horizontal component of force is used to find out the work done

[tex]W = Fdcos\theta[/tex]

so we can say the work done as

[tex]W = (Fcos\theta)d[/tex]

so here the vertical component of force is not used to find out the work done

so here it would be

[tex]F_y = Fsin\theta[/tex]

[tex]F_y = 245sin55[/tex]

[tex]F_y = 200.7 N[/tex]

so 200.7 N is not used to find out work done
