Momentum (p) is calculated using the formula:
\[ p = m \cdot v \]
where:
- \( m \) is the mass of the object (in kilograms)
- \( v \) is the velocity of the object (in meters per second)
For a 25 kg object traveling at 2.3 m/s:
\[ p = 25 , \text{kg} \cdot 2.3 , \text{m/s} \]
Calculating this gives:
\[ p = 57.5 , \text{kg m/s} \]
Therefore, the momentum of the object is 57.5 kg m/s.
