(a) g' = GM/R^2 is the value on the Moon. You will need the value of the universal gravity constant G.

It should be about 1.6 m/s^2

(b) Weight (on Moon) = M g' (in Newtons)

i take constant G is mass of the moon divided by radius square it by 2

then the weight is the mass of the person is g, g is given by the answer of part a ????????????????

G is the universal constant of gravity. Use it together with M and R to calculate g' using the formula i gave you.

If you are unfamiliar with G, read
