Final answer:
The mass of the girl on Mars would be approximately 12.95 kg.
Step-by-step explanation:
To find the mass of the girl on Mars, we can use the equation:
mMars = mEarth x (gMars/gEarth)
Given that the girl's mass on Earth is 34 kg and the acceleration due to gravity on Mars (gMars) is 3.7 m/s², and on Earth (gEarth) is 9.8 m/s², we can plug in these values to calculate the girl's mass on Mars as follows:
mMars = 34 kg x (3.7 m/s² / 9.8 m/s²) = 12.95 kg
Therefore, the mass of the girl on Mars would be approximately 12.95 kg.
