A space traveller weighs herself on Earth, at a location where the acceleration due to gravity is 9.82 m/s2, and finds a value of 571 N. What is her mass? The traveller travels to a planet in a neighboring galaxy. It is a long trip, but she somehow manages to maintain her physical condition by conscientious exercise and diet control. The acceleration due to gravity on this planet is 12.5 m/s2. What is the traveller\'s mass on the planet? and her weight there?
