To determine the new acceleration of the receiver aircraft after it receives 30,000 kg of fuel, we can use Newton's second law (F = ma).
1. **Initial conditions:**
- Mass of the receiver aircraft before refueling, \( m_1 = 110,000 \, \text{kg} \)
- Initial acceleration, \( a_1 = 4.5 \, \text{m/s}^2 \)
- Initial force, \( F = m_1 \times a_1 = 110,000 \, \text{kg} \times 4.5 \, \text{m/s}^2 = 495,000 \, \text{N} \)
2. **After
