To determine the net force acting on the object, we would need to know the direction of the forces acting on it along with their magnitudes. However, as I cannot see the image, you typically find the net force by vectorially adding the forces.

Here’s a brief guide on how to determine the net force:

  1. Identify the Forces: List the forces acting on the object along with their directions (e.g., 25 N to the right, 5 N to the left, and 10 N upward).

  2. Assign Directions: Choose a direction to be positive (common choices are to the right/up as positive and to the left/down as negative).

  3. Calculate Net Force: Add the forces together using their signs based on direction.

For example:

  • If you have:
    • 25 N to the right (+25 N)
    • 5 N to the left (-5 N)
    • 10 N upward (this would generally be considered separately if you're only looking at horizontal forces)

The calculation for the net force in the horizontal direction where horizontal forces are in play would be: \[ \text{Net Force} = +25 N + (-5 N) = 20 N \text{ to the right} \]

If you provide the directions of the listed forces, I can help you calculate the net force more accurately!

They are moving a box to the right. One pushing the top left of the box and one pushing the bottom left of the box.

Given that the box is being pushed to the right and there are two forces acting on it from the left (one from the top left and one from the bottom left), we can infer the following:

  1. Force Magnitudes:

    • Let's denote the force pushing from the top left as \( F_1 = 25 , \text{N} \).
    • Let's denote the force pushing from the bottom left as \( F_2 = 5 , \text{N} \).
    • There might also be another force \( F_3 = 10 , \text{N} \) if you are specifying it, but we need to clarify its direction as well.

  2. Direction:

    • Since the box is being pushed to the right, we can assume the forces are working against resistance or friction that may be acting to the left.

  3. Net Force Calculation:

    • If the two forces (25 N and 5 N) are indeed working to overcome a resistance and the result is to the right, we would treat these forces as pushing towards the direction we are interested in:
      • If the 25 N force is pushing more strongly than the friction or resistance, we can assume that most of its effect dominates.
      • For calculation, if we see forces as:
        • \( +25 , \text{N} \) (pushing right)
        • \( -5 , \text{N} \) (counteracting due to the force from the left)
      • The net horizontal force \( F_{net} \) would be: \[ F_{net} = 25 , \text{N} - 5 , \text{N} = 20 , \text{N} \text{ to the right} \]

If there is indeed a third force \( (10 , \text{N}) \) that's also acting in the same direction (to the right), the net force total would increase by this amount:

  • If \( 10 , \text{N} \) were also pushing the box to the right, then: \[ F_{net} = 25 , \text{N} - 5 , \text{N} + 10 , \text{N} = 30 , \text{N} \text{ to the right} \]

Please confirm the specific directions of each force, especially the 10 N force, to finalize the net force!
