Answer:
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
