additional science: physics

posted by .

Hello i have 2 questions in total.

1) The meteor enters the Earth’s atmosphere with an acceleration of approximately 9.7 m/s2 and with a force acting on it of 1.94 N. What is the mass of the meteor? Show your calculations.

2) Compare this value of the acceleration due to gravity with the most accepted value of g on the surface of the Earth of 9.8 m/s2 and suggest why there is a discrepancy in this case.

  • additional science: physics -

    m=F/g=1.94/9.7=0.2 kg
    g=GmM/(R+H)²
    g₀=GmM/R² =9.8 m/s²
