A cart weighing 200 pounds rests on an incline at an angle of 40°. What is the required force to keep the cart at rest? Round to the thousandths place.

Respuesta :

Given:

There are given that the car weighed 200 pounds on an incline at an angle of 40 degrees.

Explanation:

To find the required force, first we need to draw the triangle.

So,

Now,

We need to find the value for x:

So,

To find the value for x, we need to use the sine function.

Then,

[tex]sin40=\frac{x}{200}[/tex]

Then,

[tex]\begin{gathered} s\imaginaryI n40=\frac{x}{200} \\ x=sin40^{\circ}\times200 \\ x=128.5575 \\ x=128.558 \\ \end{gathered}[/tex]

Final answer:

Henc
