The answer to the question
Answer:
The top option is false.
Step-by-step explanation:
Both segments have a <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of ⅔. It just that their ratios have unique qualities:
![\frac{2}{3} = \frac{4}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%3D%20%5Cfrac%7B4%7D%7B6%7D)
Greatest Common Factor: 2
___ ___
<em>BC</em><em> </em>is at a 4⁄6 slope, and <em>AB</em><em> </em>is at a ⅔ slope. Although their quantities are unique, they have the exact same value.

Answer:
The constant force exerted on the ball by the wall is 119.68 N.
Step-by-step explanation:
Consider the provided information.
It is given that the mass of the ball is m = 2.2 kg
The initial velocity of the ball towards left is 7.4 m/s
So the momentum of the ball when it strikes is = ![2.2\times 7.4=16.28](https://tex.z-dn.net/?f=2.2%5Ctimes%207.4%3D16.28)
The final velocity of the ball is -6.2 m/s
So the momentum of the ball when it strikes back is = ![2.2\times -6.2=-13.64](https://tex.z-dn.net/?f=2.2%5Ctimes%20-6.2%3D-13.64)
Thus change in moment is: ![16.28-(-13.64)=29.92](https://tex.z-dn.net/?f=16.28-%28-13.64%29%3D29.92)
The duration of force exerted on the ball t = 0.25 s
Therefore, the constant force exerted on the ball by the wall is:
![\frac{29.92}{0.25}=119.68](https://tex.z-dn.net/?f=%5Cfrac%7B29.92%7D%7B0.25%7D%3D119.68)
Hence, the constant force exerted on the ball by the wall is 119.68 N.
