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

Force and Motion

Given Data

  • Weight of cart = 200 pounds
  • Angle = 40 degree

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
