Answer:

4.08 kg

Step-by-step explanation:

We can apply the Newton's second law of motion to find the mass of this object:


F=ma,

where
m is mass, and
a is acceleration, which is substituted by
g here. Now, plugging given numbers in the equation, we have


40=m\cdot9.8.

Solving for mass, we have


m=(40)/(9.8)\\=4.08 \;\text{kg}.
