Answer
1a. To determine if the forces are balanced or unbalanced, we need to compare the magnitude and direction of the forces acting on the object. According to the picture details, there is an upward force of 20N and a downward force of 25N acting on the quadrilateral.Since the forces are not equal in magnitude and are in opposite directions, the forces are unbalanced.Answer: The forces are unbalanced.1b. To find the net force, we subtract the smaller force from the larger force and take the direction of the larger force. In this case, the larger force is the downward force of 25N, and the smaller force is the upward force of 20N.Net Force = Larger force - Smaller forceNet Force = 25N (downward) - 20N (upward)Now, calculate the net force:Net Force = 5N (downward)Answer: The net force on the object is 5N in the downward direction.2. Since I cannot draw in this format, I will describe how to draw a free body diagram for Ms. Elizabeth pushing a trash can across the cafeteria floor:- Start by drawing a box to represent the trash can.- Draw an arrow pointing downward from the center of the box, and label it "force of gravity" or "weight."- Draw an arrow starting from the point where the box touches the "floor" and pointing upward; label this "normal force."- Draw an arrow on one side of the box pointing to the right (assuming she is pushing from left to right); label this "applied force."- Draw a smaller arrow on the same side as the applied force but pointing to the left; label this "friction."You do not need to include spring force or tension force in this diagram, as they are not relevant to the scenario described.Remember, the length of the arrows should represent the relative magnitude of the forces. The force of gravity and normal force will typically be equal in magnitude if the trash can is not accelerating vertically, while the applied force and friction will depend on how hard Ms. Elizabeth is pushing and the friction between the trash can and the floor.
