<h2>Answer:</h2>

Driver experiences 17.68 G's on an average.

<h2>Step-by-step explanation:</h2>

In the question,

We know that in a car crash the speed of the car goes from the speed of 26 m/s to 0 m/s in 0.15 seconds.

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

a = -173.33 m/s²

As, there is deceleration of the car is taking place the acceleration is in negative.

Now,

To convert it into the force in the G's we need to divide the deceleration by the acceleration (gravity), g.

So,

G's experienced by the driver on an average is given by,

$\frac{173.33}{9.8}=17.68$

Therefore, on an average the driver experiences 17.68 G's.

M is directly proportional to r^3

Oliga [24]

Answer:

r=6

Step-by-step explanation:

Proportions

We know M is directly proportional to $r^3$

This can be written as

$M=kr^3$

Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:

$160=k\cdot 4^3$

$160=k\cdot 64$

Solving for k:

$k=\frac{160}{64}=2.5$

The equation is:

$M=2.5\cdot r^3$

Now find r when M=540:

$540=2.5\cdot r^3$

Dividing by 2.5:

$216=r^3$

Taking cube roots:

$r=\sqrt[3]{216}$

r=6
