Adog pulls on a pillow with a force of 5 n at an angle of 37o to the horizontal. find the x and y components of this force.

x- component = Fx= 4N

y - component= Fy= 3N

Explanation:

Fx=Fcos∅= 5cos 37= 3.99≅4N

Fy=F sin∅= 5 Sin37= 3.009≅3.01N

the dog pulls the pillow at an angle 37 degrees to the horizontal means it pulls it at an angle 37 degrees with the x- axis.if  the line of the force represents the vector F then its horizonatal and vertical components wil be along x-axis and y-axis ie Fx and Fy.

as sin∅= Perpendicular/ Hypotenuse

but we have force F and Fy

so sin∅= Fy/F

or Fy= Fsin∅eqA

similarly cos∅= base /hpotenuse

cos∅= Fx/F

Fx= Fcos∅eq B

eq A  and eq B can be used to determine the values of the rectangular components of the force making an angle with the horizontal

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
