Momentum is mass times velocity of the object

p = m • v

p = (7700 kg)(14 m/s)

p = 107809 kg m/s

Answer:

4.08 kg

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

$m=\frac{40}{9.8}\\=4.08 \;\text{kg}.$
