Answer:

Part a)

Weight on surface of other planet = 213.4 N

Part b)

Mass of the Astronaut = 66.0 kg

Part c)

Weight of the Astronaut on Earth = 646.8 N

Explanation:

Part A)

Weight of the Astronaut on the surface of the planet is given as

[tex]F_g = mg[/tex]

here we will have

[tex]m = 66.0 kg[/tex]

also we have

[tex]g = 0.33(9.8) m/s^2[/tex]

[tex]g = 3.23 m/s^2[/tex]

now we have

[tex]F = 66 \times 3.23 = 213.4 N[/tex]

Part B)

Mass of the Astronaut will always remains the same

So it will be same at all positions and all planets

So its mass will be

m = 66.0 kg

Part C)

Weight of the Astronaut on Earth is given as

[tex]F_g = mg[/tex]

[tex]F_g = (66.0 kg)(9.8 m/s^2)[/tex]

[tex]F_g = 646.8 N[/tex]
