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.

Your answer will be Alkali Metals.Because the alkali metals make up Group 1 of the table, and comprise lithium(Li) through francium(Fr).
Answer is d. The material can be phsycal changes into a differnt shape or state (gas, liquid, solid) and its will still be essentially copper. A chemical change is changing what other elements or compound is bonded to the copper atoms
