Answer:</h2>
<em><u>Driver experiences 17.68 G's on an average.</u></em>
<h2>
Step-by-step explanation:</h2>
In the question,
We know that in a car crash the speed of the car goes from the <u>speed of 26 m/s to 0 m/s</u> in <u>0.15 seconds</u>.
So,
The final speed, v = 0 m/s
Initial speed, u = 26 m/s
Also,
Time in seconds, t = 0.15 s
So,
Using the equation of law of the motion, we get,
v = u + at
0 = 26 + a(0.15)
a = -26/0.15
<u>a = -173.33 m/s²</u>
As, there is deceleration of the car is taking place the acceleration is in negative.
Now,
To convert it into the force in the <u>G's</u> we need to divide the <u>deceleration</u> by the <u>acceleration (gravity), g.</u>
So,
<u>G's experienced by the driver on an average</u> is given by,
<em><u>Therefore, on an average the driver experiences 17.68 G's.</u></em>
Answer:
Smallest to largest
Step-by-step explanation
4/3, square root of 2, 1.423..., pie, 1.666...., square root of 4
I found width=13.72 ft and length=43.72 ft.
Call one dimension of the rectangle x, the other will be x+30
You want an area A=600 ft^2 but A=length x width=x*(x+30)=600
Rearranging you get:
solving this quadratic equation you get a negative solution and a positive one that gives your result.
A system is inconsistent when there are no solutions between the two equations. Graphically, the lines will be parallel (they never meet!) and the slopes will be the same. But the y-intercepts will be different.
Let's look at the four equations, with each solved as needed, into y = mx + b form.
A: 2x + y = 5
y = 5 - 2x
y = -2x + 5
Compared to y = 2x + 5, the slopes are different, so this system won't be inconsistent. Not a good choice.
B: y = 2x + 5
Compared to y = 2x + 5, the slopes are the same and the y intercepts are the same. This system has infinitely many solutions. Not a good choice.
C: 2x - 4y = 10
-4y = 10 - 2x
-4y = -2x + 10
y = 2/4x -10/4
Here the slopes are different, so, like A this is not a good choice.
D: 2y - 4x = -10
2y = =10 + 4x
2y = 4x - 10
y = 2x - 5
Compared to y = 2x + 5 we have the same slopes and different y intercepts. The lines will be parallel and the system is inconsistent.
Thus, D is the best choice.
