Someone's weight while standing on the Earth's surface is m x g, where g has the familiar surface value of 9.80 m/s^2. Suppose, while on a space mission, you find yourself in space at a heigh of 1/6 Radius of earth above the surface of the Earth. Find an algebraic epxression for your weight at that alitude, in terms of m and g. Please show work.
