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
- 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.

<h2>Hello!</h2>
The answer is:
The third option, 79.8%
<h2>Why?</h2>To calculate the percent yield we need to divide the actual yield by the theoretical yield, and then, multiply it by 100 in order to find the percent.
So, we from the statement we know the following information:
Let's use the following formula and substitute the given information:
Hence, we have that the correct option is the third option, the percent yield is 79.8%.
Have a nice day!
