Momentum (p) is calculated using the formula:
\[
p = m \cdot v
\]
where:
- \( m \) is the mass in kilograms (kg),
- \( v \) is the velocity in meters per second (m/s).
Given:
- Mass of the elephant \( m = 2000 \) kg,
- Velocity of the elephant \( v = 7.5 \) m/s.
Now, substituting the values into the formula:
\[
p = 2000 \, \text{kg} \cdot 7.5 \, \text{m/s} = 15000 \, \text{kg} \cdot \text{m/s}
\]
Therefore, the momentum of the elephant is \( 15000 \, \text{kg} \cdot \text{m/s} \).
\[
p = m \cdot v
\]
where:
- \( m \) is the mass in kilograms (kg),
- \( v \) is the velocity in meters per second (m/s).
Given:
- Mass of the elephant \( m = 2000 \) kg,
- Velocity of the elephant \( v = 7.5 \) m/s.
Now, substituting the values into the formula:
\[
p = 2000 \, \text{kg} \cdot 7.5 \, \text{m/s} = 15000 \, \text{kg} \cdot \text{m/s}
\]
Therefore, the momentum of the elephant is \( 15000 \, \text{kg} \cdot \text{m/s} \).
