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

$40=m\cdot9.8$ .

Solving for mass, we have

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