Momentum is calculated using the formula:
\[
\text{Momentum} = \text{mass} \times \text{velocity}
\]
Given that the mass of the book is 5 kg and the velocity is 2 m/s, we can substitute these values into the formula:
\[
\text{Momentum} = 5 \, \text{kg} \times 2 \, \text{m/s} = 10 \, \text{kg-m/s}
\]
Thus, the momentum of the book is:
**A) 10 kg-m/s**
\[
\text{Momentum} = \text{mass} \times \text{velocity}
\]
Given that the mass of the book is 5 kg and the velocity is 2 m/s, we can substitute these values into the formula:

Thus, the momentum of the book is:
