<h2>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>
