a man is pulling on his dog with a force of 70.0 N directed at an angle of +30.0° to the horizontal. Find a the x and y components of this force
for the horizontal (x) component: use Fx=F(cosФ)
Fx= 70N (cos 30°) = 60.6 N
for the vertical (y) component: use Fy=F(sinФ)
Fx= 70N (sin 30°) = 35.5 N
Answer
x-component = 35.0 N
y-component = 60.62 N
Explanation
The x-component (Fx) of 70.0 N can be found using the trigonometric ratio sine.
sin = opposite/hypotenuse
sin30 = \(\frac{Fx}{70}\)
Fx = 70 × sin30
= 35 N
The y-component (Fy) of 70.0 N can be found using the trigonometric ratio cosine.
cos30 = \(\frac{Fy}{70}\)
Fy = 70 × cos30
= 60.62 N
