A child pulls a sled through the snow on a level path with a force of 20 N exerted at an angle of pi/4 above the horizontal. Find the horizontal and vertical components of the force (expressed as vectors).

Answer:

[tex]10\sqrt 2 iN[/tex] and [tex]10\sqrt 2 jN[/tex]

Step-by-step explanation:

We are given that

Force =F=20 N

[tex]\theta=\frac{\pi}{4}[/tex]

We have to find the horizontal and vertical component of the force.

Horizontal component of the force =[tex]F_x=Fcos\theta i[/tex]

Horizontal component of the force=[tex]F_x=20cos\frac{\pi}{4}i=10\sqrt 2 iN[/tex]

Vertical component of the force,[tex]F_y=Fsin\theta j[/tex]

Vertical component of the force,[tex]F_y=20sin\frac{\pi}{4}j=10\sqrt 2 jN[/tex]

Force,[tex]F=F_x+F_y[/tex]

[tex]F=10\sqrt 2i N+10\sqrt 2j N[/tex]
