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:



Step-by-step explanation:
Represent:
- The opposite with a
- The adjacent with b
- The hypotenuse with c
Given that:


Required
Solve for a, b and c

So, we have:

Subtract 1 from both sides


Apply Pythagoras Theorem

Substitute 3 + 3b for a and 4 + 3b for c

But the adjacent of a triangle can't have a negative measurement.
So:

Recall that:


Substitute 7 for b in the above expressions






Hence, the dimensions of the triangle are:

Answer:
$12
Step-by-step explanation:
3 cars divide that by $18 and u get $6 per car. multiply that by two cars nd you get $12.
Ratio triangle height to square side 7:8
ratio triangle base to square side 1:2
Area of the square is 64 in² then the sides = 8 in
ratios give
h = 7(8)/8
h = 7
b = 8/2
b = 4
Area Triangle = 0.5(7)(4)
= 14
Then shaded region is the Area of the square minus the Area of the triangle.
A = 64 - 14
A = 50 in²
