The force needed to keep the cart at rest is 149.022 pounds

<h3>Force and Motion</h3>

Given Data

The force needed to keep the cart at rest is the vertical component of the resultant force, hence we have

Fy = Mg sin θ

Substituting our given data we have

Fy = 200 sin 40

Fy = 200 *0.74511

Fy = 149.022 pounds
