To calculate the momentum (p) of an object, you can use the formula:
\[ p = m \times v \]
where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
In this case, the mass \( m = 5 , \text{kg} \) and the velocity \( v = 20 , \text{m/s} \).
Now, plug in the values:
\[ p = 5 , \text{kg} \times 20 , \text{m/s} = 100 , \text{kg} \cdot \text{m/s} \]
So, the momentum of the object is 100 kg⋅m/s.
