Ответ$$g = 3.74404586625655\,{\text{м/с}}^2$$
$$g = 0.00374404586625655\,{\text{км/с}}^2$$
$$g = 48522834.4266849\,{\text{м/ч}}^2$$
$$g = 48522.8344266849\,{\text{км/ч}}^2$$Решение$$m = 0.056\, M_\oplus = 3.34441408\cdot 10^{23}\, \text{кг}$$
$$r = 2439.7\, \text{км} = 2439700\, \text{м}$$
$$h = 2\, \text{км} = 2000\, \text{м}$$
$$g = \dfrac{GM}{(r+h)^2} = $$$$\dfrac{6.67430 \cdot 10^{-11} \cdot 3.34441408\cdot 10^{23}}{\left(2439700+2000\right)^2} = $$ $$3.74404586625655\,{\text{м/с}}^2$$
