Question
![### Problem Statement
**Given:**
The door has a weight of 230 lb and a center of gravity at point \( G \).
#### Figure Description:
- The figure illustrates a door with the following dimensions and descriptions:
- The width of the door is 10 ft.
- The height of the door is 7 ft.
- The door is being pushed open by a person applying force.
- The force \( F \) is applied to push the door to the right.
- Points of interest are located:
- \( A \) is the roller at the bottom of the left side of the door.
- \( B \) is the roller at the bottom of the right side of the door.
- The center of gravity \( G \) is positioned at the center vertically and horizontally within the door's dimensions.
### Part A
Determine the constant force \( F \) that must be applied to the door to push it open 10 ft to the right in 5 s, starting from rest.
**Express your answer to three significant figures and include the appropriate units.**
