Answer: Mass on the moon = 60 kg; weight on the moon = 96 N.

Mass is the amount of matter in a body, so it does not change from place to place: mass on the moon = 60 kg.

Weight on the moon:

\[W_m = m\,g_m = 60\ \text{kg} \times 1.6\ \text{m/s}^2 = 96\ \text{N}\]

(On the earth his weight would be \(60 \times 9.8 = 588\) N, so his weight on the moon is about one-sixth of that.)
