Four movers pick up boxes. Each box has a different mass, and each mover applies a different amount of force to lift the box. Which box will have the greatest acceleration? (1 point)
• a 20 kg box lifted with 60 N of force
• a 10 kg box lifted with 40 N of force
• a 10 kg box lifted with 60 N of force
• a 20 kg box lifted with 40 N of force

Acceleration a = (F - mg)/m = F/m - g, so compare F/m for each:
- 20 kg, 60 N: F/m = 3 N/kg
- 10 kg, 40 N: F/m = 4 N/kg
- 10 kg, 60 N: F/m = 6 N/kg
- 20 kg, 40 N: F/m = 2 N/kg
The largest F/m is 6 N/kg, so the 10 kg box lifted with 60 N has the greatest acceleration.
- 20 kg, 60 N: F/m = 3 N/kg
- 10 kg, 40 N: F/m = 4 N/kg
- 10 kg, 60 N: F/m = 6 N/kg
- 20 kg, 40 N: F/m = 2 N/kg
The largest F/m is 6 N/kg, so the 10 kg box lifted with 60 N has the greatest acceleration.
