Weight of 80.6kg Astronaut on Mars: 294N (3 sig figs)

AI Thread Summary
To calculate the weight of an 80.6 kg astronaut on Mars, the formula weight equals mass times acceleration (W = m * g) is used, where the acceleration due to gravity on Mars is 3.70 m/s². Multiplying 80.6 kg by 3.70 m/s² results in a weight of 298.22 N. Rounding to three significant figures, the weight is 294 N. The mass of the astronaut remains constant regardless of the planet, making the calculation straightforward. Understanding the relationship between mass and weight is key to solving such problems.

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

Precisely.

Isn't there a simple relationship between mass and weight?
 
Mass times acceleration is weight right? So would it just be 80.6 times 3.7?
 
Exactly :smile:
 
Hmm, I feel silly for not putting two and two together. Haha, thanks though!
