Question

What is the momentum of a 5 kg object that has a velocity of 1.2 m/s?

3.8 kg • m/s
4.2 kg • m/s
6.0 kg • m/s
6.2 kg • m/s

Answer 1

The momentum \( p \) of an object is calculated using the formula:

\[
p = m \cdot v
\]

where \( m \) is the mass of the object, and \( v \) is its velocity.

Given:
- Mass \( m = 5 \) kg
- Velocity \( v = 1.2 \) m/s

Now, we can substitute the values into the formula:

\[
p = 5 \, \text{kg} \cdot 1.2 \, \text{m/s} = 6.0 \, \text{kg} \cdot \text{m/s}
\]

Thus, the momentum of the object is **6.0 kg • m/s**.
