To determine the net force acting on the block, we can analyze the forces being applied in both the north-south and east-west directions.
Forces in the north-south direction:
- Allie pushes to the north with 18 N.
- Chris pushes to the south with 23 N.
Net force in the north-south direction: \[ \text{Net North-South Force} = 18 , \text{N (north)} - 23 , \text{N (south)} = -5 , \text{N} \] This indicates a net force of 5 N to the south.
Forces in the east-west direction:
- Bill pushes to the east with 14 N.
- Debra pushes to the west with 20 N.
Net force in the east-west direction: \[ \text{Net East-West Force} = 14 , \text{N (east)} - 20 , \text{N (west)} = -6 , \text{N} \] This indicates a net force of 6 N to the west.
Final Result: The net forces indicate that the block will move to the south and west.
So, the correct response is south and west.
