# A rubber ball with a mass of \(0.25 \, \text{kg}\) and a speed of \(19.0 \, \text{m/s}\) collides perpendicularly with a wall and bounces off with a speed of \(21 \, \text{m/s}\) in the opposite direction. What is the magnitude of the impulse acting on the rubber ball?

A rubber ball with a mass of \(0.25 \, \text{kg}\) and a speed of \(19.0 \, \text{m/s}\) collides perpendicularly with a wall and bounces off with a speed of \(21 \, \text{m/s}\) in the opposite direction. What is the magnitude of the impulse acting on the rubber ball?

- **A.** \(0 \, \frac{\text{kg} \cdot \text{m}}{\text{s}}\)
- **B.** \(.5 \, \frac{\text{kg} \cdot \text{m}}{\text{s}}\)
- **C.** \(5 \, \frac{\text{kg} \cdot \text{m}}{\text{s}}\)
- **D.** \(10 \, \frac{\text{kg} \cdot \text{m}}{\text{s}}\)
- **E.** \(20 \, \frac{\text{kg} \cdot \text{m}}{\text{s}}\)
