The momentum (p) of an object can be calculated using the formula:
\[ p = m \cdot v \]
where:
- \( p \) is the momentum,
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
In this case, the mass \( m \) of the ball is 1.5 kg and its velocity \( v \) is 3.0 m/s.
Now, substituting the values into the formula:
\[ p = 1.5 \, \text{kg} \cdot 3.0 \, \text{m/s} \]
\[ p = 4.5 \, \text{kg} \cdot \text{m/s} \]
So, the momentum of the ball is 4.5 kg·m/s.
\[ p = m \cdot v \]
where:
- \( p \) is the momentum,
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
In this case, the mass \( m \) of the ball is 1.5 kg and its velocity \( v \) is 3.0 m/s.
Now, substituting the values into the formula:
\[ p = 1.5 \, \text{kg} \cdot 3.0 \, \text{m/s} \]
\[ p = 4.5 \, \text{kg} \cdot \text{m/s} \]
So, the momentum of the ball is 4.5 kg·m/s.
