Answer :
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
