The Moon has a mass of 7.36 1022 kg and a radius of 1.74 106 m.
(a) What is the acceleration due to gravity on the Moon
b) How much would a 4.03 kg person weigh on this planet

• Physics -

(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)

• Physics -

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 ????????????????

• Physics -

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
