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 543 N. What is her mass m? The traveller travels to a planet in a neighboring solar system. 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 13.9 m/s². What are the traveller's weight w and mass m' on the planet? W = m = N m' = kg kg
