91 kg & 150 N

Explanation:

Given:

m = 91 kg

W = 900 N

The force of gravity on Earth = 6 x The force of gravity on Moon

To Find:

(i) What is the mass of the astronaut on the Moon?

(ii) What is the weight of the astronaut on the Moon? Show your calculations

Solution:

(i) The mass of the astronaut on the Moon = The mass of the astronaut on the Earth = 91 kg (Since mass is constant)

(ii) The weight of the astronaut on the Moon = The weight of the astronaut on the Earth/6

The weight of the astronaut on the Moon = 900 / 6

The weight of the astronaut on the Moon = 150 N
