Answer:
m = 3.8 kg
Step-by-step explanation:
The weight can be calculated as follows:

Where m is the mass and g is the gravity. So, replacing the weight by 37 N and the gravity by 9.8 m/s², we get:

So, solving for m, we get:
![\begin{gathered} (37)/(9.8)=(m\cdot9.8)/(9.8) \\ 3.8\operatorname{kg}\text{ = m} \end{gathered}]()
Therefore, the answer is m = 3.8 kg
