Answer: Choice A ![-4 \le x \le -2](https://tex.z-dn.net/?f=-4%20%5Cle%20x%20%5Cle%20-2)
</h3>
Explanation:
Ask yourself this: "When is the graph completely horizontally flat?" The answer to this question is when x is between -4 and -2. This is where the graph is constant. All other intervals are either increasing or decreasing.
Saying "The graph is constant" basically means "constant rate of change", which is another way of saying that the graph isn't changing. Constant means it stays the same.
So this is why the answer is ![-4 \le x \le -2](https://tex.z-dn.net/?f=-4%20%5Cle%20x%20%5Cle%20-2)
Note how only choice A has both endpoints in the negative region, so it is a quick way to spot the answer.
21 picks
altogether (2x+5x)=21
7x=21
x=3
2*3=6 orange picks
or
x=orange, y = greens
x+y=21
x/y=2/5,----> y=5x/2
x+5x/2=21
2x/2+5x/2=21
7x/2=21
7x=42,
x=6 orange picks
The average force exerted by the block exists at -375 N.

How to find the average force exerted by the block?</h3>
Given:
Initial Velocity, u = 50m/s
Displacement, s = 10cm = 0.10m
Mass, m = 0.03Kg
Using the relation,
![$v^{2}-u^{2}=2 a s](https://tex.z-dn.net/?f=%24v%5E%7B2%7D-u%5E%7B2%7D%3D2%20a%20s)
Substitute the values in the above equation, we get:
![$&0^{2}-50^{2}=2 \mathrm{a}(0.10) \\](https://tex.z-dn.net/?f=%24%260%5E%7B2%7D-50%5E%7B2%7D%3D2%20%5Cmathrm%7Ba%7D%280.10%29%20%5C%5C)
![$ \mathrm{a}= -12500 \mathrm{~ms}^{-2}](https://tex.z-dn.net/?f=%24%20%5Cmathrm%7Ba%7D%3D%20-12500%20%5Cmathrm%7B~ms%7D%5E%7B-2%7D)
We know that, f = ma
Putting the values, we get:
f = (0.03)(-12500)
f = -375 N
The average force exerted by the block exists at -375 N.
