# A car of mass \( 1500 \) \( \text{kg} \) is traveling at one of the speeds listed when the brakes are first applied. Using the data above, what is the magnitude of the average braking force required to stop the car?

| **Speed** | \( 10 \, \mathrm{m/s} \) | \( 20 \, \mathrm{m/s} \) | \( 30 \, \mathrm{m/s} \) |
| --- | --- | --- | --- |
| **Braking Distance** | \( 6.1 \, \mathrm{m} \) | \( 23.9 \, \mathrm{m} \) | \( 53.5 \, \mathrm{m} \) |

A car of mass \( 1500 \, \mathrm{kg} \) is traveling at one of the speeds listed when the brakes are first applied. Using the data above, what is the magnitude of the average braking force required to stop the car?

- **A.** \[ 75{,}000 \, \text{N}\]
- **B.** \[ 30{,}000 \,\text{N} \]
- **C.** \[ 12{,}000 \,\text{N} \]
- **D.** \[ 1600 \,\text{N} \]
