Air friction gravity and yeayayayayayya
I think you're supposed to use a formula that helps you find the weight in the first exercise and the mass in the second exercise on the Earth and the Moon. Keep in mind that in physics mass and weight mean different things.
I hope my answer helped u under stand better
