Answer:
Mass=0.305[kg]
Explanation:
The block is located on a surface, where no forces act on it, so it will remain at rest according to Newton's laws.
We can perform an analysis of forces on the y-axis (see the free body diagram) and in order to determine the equation to determine the mass of the body, we must remember that the value of a force influenced by gravity is equal to the product of mass by acceleration.
From this equation we can clear the value of the mass
