Solution: The value of x after solving both components is or
.
Explanation:
From the first component it is clearly noticed that the value of x is greater than 2.
Simplify the second component.
From the above inequality it is clearly noticed that the value of x is less than or equal to 11.
Solving both components we get and the graphical representation is shown in the figure.
The red portion shows the solutions of , blue portion shows the solution of
and purple portion which combination of red and blue portion shows the solution of both inequalities.
Therefore, value of x after solving both components is or
.
First, illustrate the problem into a diagram like the one shown in the attached picture. The component vectors are shown in red (y-component) and blue (x-component). Since this is a right triangle, let's apply the trigonometric functions of sine and cos.
y-component, vy:
sin (π/3) = vy/8
vy = 6.928
x-component, vx:
cos (π/3) = vx/8
vx = 4
y-component, vy:
sin (π/3) = vy/8
vy = 6.928
x-component, vx:
cos (π/3) = vx/8
vx = 4
