Use a = (F − mg)/m = F/m − g.

Compute F/m for each:
- 10 kg, 60 N: F/m = 6 → a = 6 − 9.8 = −3.8 m/s²
- 20 kg, 60 N: F/m = 3 → a = 3 − 9.8 = −6.8 m/s²
- 10 kg, 40 N: F/m = 4 → a = 4 − 9.8 = −5.8 m/s²
- 20 kg, 40 N: F/m = 2 → a = 2 − 9.8 = −7.8 m/s²

The greatest acceleration (largest value) is −3.8 m/s², so the 10 kg box lifted with 60 N.
