Answer to Question #147395 in Physics for david

Question

We are seated on the surface of the earth. What is the gravitational strength of the earth on you if the mass of the earth is 5.9x1024kg and a radius of 6.4x106 m?

Answer 1

$$g=\frac{GM}{R^2}\\g=\frac{(6.67\cdot10^{-11})(5.9\cdot10^{24})}{(6.4\cdot10^{6})^2}=9.6\frac{m}{s^2}$$
