The weight of a rock on the moon is 0.85 N. If acceleration due to gravity on the moon is 1.7 m/s2, what will be its weight on the earth

Answer 1

weight = mg, so, if g doubles, so does weight.

so, weight on earth is .85 * (9.8/1.7) = 4.9 N

how boring. surely they didn't have to make the values come out so normal.
