Question

6) The acceleration due to gravity on Mars surface is 37.9% of that on Earth. An

astronaut's life support backpack weighs 300 lb on Earth. What does it weigh on the
Red Planet?

Answer 1

Weight is directly proportional to the acceleration of gravity wherever you happen to be at the moment.

If the backpack weighs 300 lb on Earth, and you take it to a place where gravity is 37.9% of Earth's gravity, then the backpack will weigh

(37.9%) x (300 lb)

(0.379) x (300 lb)

That's 113.7 lb.
