Answer

The acceleration due to gravity (free fall) is approximately 9.81 m/s29.81 \, \text{m/s}^2. Reviewing the provided options:

  • A: 8.8 m/s28.8 \, \text{m/s}^2
  • B: 9.8 m/s29.8 \, \text{m/s}^2
  • C: 10.8 m/s210.8 \, \text{m/s}^2
  • D: 11.8 m/s211.8 \, \text{m/s}^2

Among these, option B (9.8 m/s²) is the closest to the accepted value of 9.81 m/s². Therefore, the correct answer is B.
