Answer :
Final answer:
The mass of your friends is 92 kg.
Explanation:
To find the mass of your friends, we can use Newton's second law of motion, which states that force is equal to the mass of an object multiplied by its acceleration. Rearranging the formula, we have mass = force / acceleration. Plugging in the given values, we get mass = 120 N / 1.3 m/s² = 92 kg.
