1. The problem statement, all variables and given/known data How can I find mass when weight and distance is given.(Note I can't use 9.8m/s^2 as my acceleration of gravity because the question is dealing distances that are extremely high from earth's surface.And also how can i find the right acceleration at such heights? 2. Relevant equations F=ma 3. The attempt at a solution am stuck cos I know i can't use 9.8m/s^2.
