To calculate the momentum of Amy riding the skateboard, you can use the formula for momentum:
\[ \text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v) \]
Given:
- Mass (m) = 50 kg
- Velocity (v) = 10 m/s
Now, plug in the values:
\[ p = 50 , \text{kg} \times 10 , \text{m/s} = 500 , \text{kg} \cdot \text{m/s} \]
Therefore, the momentum is 500 kg⋅m/s.
