Answer:
The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.
Step-by-step explanation:
From Newton's Law of Motion, the weight (
), measured in newtons, of an object is defined by this expression:
(1)
Where:
- Mass, measured in kilograms.
- Gravitational acceleration, measured in meters per square second.
The gravitational acceleration in Callisto is 1.236 meters per square second.
If we know that
and
, then the weight of the astronaut in Callisto is:


And the fraction is:


The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.
