Answer:
m = 60 [kg] (mass on the moon)
Step-by-step explanation:
We must remember that the mass is conserved, that is, it remains the same regardless of where it is located.
The only variation is the weight, which is different from the mass. Weight is determined by means of the product of mass by gravitational acceleration.
Therefore the mass of 60 [kg] on Earth will be the same mass on the moon.
