2 mass problems help!?
a space traveler weighs herself on Earth, at a location where the acceleration due to gravity is 9.81m/s^2 and finds a value of 561N. What's her mass?
the traveler travels to another planet. the acceleration due to gravity on this planet is 12.3m/s^2
whats her mass AND weight?

Well,
weight = m g
561 = m * 9.81
m = 561 / 9.81 = 57.19 Kg
On the other planet, her mass doesn't change, so remains as 57.19 Kg
weight on other planet = m g = 57.19 * 12.3 = 703.44 N
