Answer 1

Momentum (p) is calculated using the formula:

\[ p = m \times v \]

where:
- \( m \) is the mass of the object (in kilograms),
- \( v \) is the velocity of the object (in meters per second).

For the football player:

- Mass \( m = 97 \, \text{kg} \)
- Velocity \( v = 8 \, \text{m/s} \)

Now, plug in the values:

\[ p = 97 \, \text{kg} \times 8 \, \text{m/s} = 776 \, \text{kg} \cdot \text{m/s} \]

So, the momentum of the football player is **776 kg·m/s**.
