To determine the momentum of the book, we use the formula for momentum:
[tex]\[ p = mv \][/tex]
where
- [tex]\( p \)[/tex] represents momentum,
- [tex]\( m \)[/tex] represents mass, and
- [tex]\( v \)[/tex] represents velocity.
Given:
- The mass ([tex]\( m \)[/tex]) of the book is [tex]\( 5 \)[/tex] kg.
- The velocity ([tex]\( v \)[/tex]) of the book is [tex]\( 2 \)[/tex] m/s.
Let's plug in the values into the formula:
[tex]\[ p = 5 \, \text{kg} \times 2 \, \text{m/s} \][/tex]
Now, perform the multiplication:
[tex]\[ p = 10 \, \text{kg} \cdot \text{m/s} \][/tex]
Thus, the momentum of the book is:
[tex]\[ 10 \, \text{kg} \cdot \text{m/s} \][/tex]
So, the correct answer is:
B. [tex]\( 10 \, \text{kg} \cdot \text{m/s} \)[/tex]
