8. Jax bounced a dodgeball off a wall. The dodgeball has a momentum of 32.6 kg · m/s after the collision. What is the total momentum of the system before the collision?

Explanation:

= Final momentum of the system =

According to the principle of conservation of angular momentum we have

The wall is not moving so the initial and final momentum of the system are equal.

So, the total momentum of the system before the collision is .

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
