Question
On the surface of the Moon an astronaut has a weight of Fg = 120 N. The radius of the Moon is Rm = 1.74 x 106 m, the gravitational constant is G = 6.67 x 10-11 N m2kg2 and the mass of the Moon is Mm = 7.35 x 1022 kg.
Solve numerically for the mass of the astronaut ma in kg

Well, you have the formula
F = GMm/r^2
So, plug in the numbers. What do you get?
Oh, OK. The astronaut's mass is thus
m = Fr^2/GM
F = GMm/r^2
So, plug in the numbers. What do you get?
Oh, OK. The astronaut's mass is thus
m = Fr^2/GM

Ok steve so I did 120(1.74x10^6)/(6.67x10^-11)(7.35x10^22)=2.300869565E19
