Answer:

Step-by-step explanation:
This problem refers to the Newton's second law, and it describes how a body with mass can release its force while this changes its velocity over time. The formula that describes this relationship is:

Where f stands for force (measured in N or Newtons)
m stands for mass (measured in Kg or Kilograms)
a stands for acceleration (
)
So, in order to obtain the mass from this formula, we just need to isolate m.
The final result is:
