To calculate the momentum of an object, you can use the formula:
\[
\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)
\]
In this case, the mass \( m \) of the train is 12,000,000 kg and the velocity \( v \) is 10 m/s.
Now plug in the values:
\[
p = 12,000,000 \, \text{kg} \times 10 \, \text{m/s}
\]
\[
p = 120,000,000 \, \text{kg m/s}
\]
So, the momentum of the train is **120,000,000 kg m/s** (or \( 1.2 \times 10^8 \, \text{kg m/s} \)).
\[
\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)
\]
In this case, the mass \( m \) of the train is 12,000,000 kg and the velocity \( v \) is 10 m/s.
Now plug in the values:
\[
p = 12,000,000 \, \text{kg} \times 10 \, \text{m/s}
\]
\[
p = 120,000,000 \, \text{kg m/s}
\]
So, the momentum of the train is **120,000,000 kg m/s** (or \( 1.2 \times 10^8 \, \text{kg m/s} \)).
