Weight of an 80.6 kg astronaut on Mars

[fattydq]

What is the weight in Newtons of a 80.6 kg astronaut on Mars where the acceleration due to gravity is 3.70 m/s^2. Give answer with 3 sig figs only

Could I just use a ratio? Like 9.8/80.6 is equal to 3.7/? or is that over simplifying the problem?

Is the mass of the astronaut different on Mars?

 

[fattydq]

No. But how is that relevant it's asking about weight...?

Precisely.

Isn't there a simple relationship between mass and weight?

 

[fattydq]

Mass times acceleration is weight right? So would it just be 80.6 times 3.7?

Exactly

Hmm, I feel silly for not putting two and two together. Haha, thanks though!
