Question

A soccer ball with a mass of 0.45kg is kicked and moves with a velocity of 8 m/s. What id the balls momentum.

3.8n
7.6n
4.5n
3.6n

Answer 1

To calculate the momentum of the soccer ball, you can use the formula for momentum:

\[
\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)
\]

Given:
- Mass \( m = 0.45 \, \text{kg} \)
- Velocity \( v = 8 \, \text{m/s} \)

Now, plug in the values:

\[
p = 0.45 \, \text{kg} \times 8 \, \text{m/s} = 3.6 \, \text{kg} \cdot \text{m/s}
\]

Based on the options provided:

- 3.8 N (Not correct)
- 7.6 N (Not correct)
- 4.5 N (Not correct)
- 3.6 N (Correct)

The correct answer is 3.6 N (or more correctly, 3.6 kg·m/s if you are speaking of momentum, but in the context of the options provided, it seems they are asking in terms of Newtons which is not standard for momentum) .
