The final velocity of Bill after he catches the pillow is 4.44 m/s.
The given parameters:
- Mass of Bill, m1 = 77 kg
- Velocity of Bill, u1 = 2.6 m/s
- Mass of the pillow, m2 = 6.9 kg
- Initial velocity of the pillow, u2 = 25 m/s
<h3>What is conservation of linear momentum?</h3>
- The principle of conservation of linear momentum states that the total momentum of an isolated system is constant.
The final velocity of Bill is determined by applying the principle of conservation of linear momentum as follows;
Thus, the final velocity of Bill after he catches the pillow is 4.44 m/s.

The answer is c electrostatic repulsion between nuclei
D. Cell membrane: surrounds a cell and allows substances to pass in and out
Answer:
A. particles are the same.
Explanation:
Hello, since we are talking about the water, the molecules are quite equal.
Nonetheless, if you want to know it (because this is not in the answers), the particles move faster in the boiling water than in the ice, considering that in the boiling water there is a larger energy content, which allows the molecules to move faster (they "have" more energy). In addition, The molecules are closer in the ice because that is the only way for them to solidify (get together).
Best regards!
