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 60 N of force

a 10 kg box lifted with 40 N of force

a 20 kg box lifted with 40 N of force

Use a = (F - mg)/m = F/m - g, so compare F/m. Values:

- 60/20 = 3
- 60/10 = 6 ← largest
- 40/10 = 4
- 40/20 = 2

So the 10 kg box lifted with 60 N has the greatest acceleration (a = (60 − 98)/10 = −3.8 m/s², i.e. the least downward acceleration).
