What should happen to the demand for speed (measured by the average speed on highways) once airbags are included on cars?

1 answer:

6 0

Airbags diminish the expenses related with driving quick by diminishing injuries caused by fast speed crashes, in this manner the demand for speed increases, raising the average speed. Subsequently, wellbeing gadgets, for example, airbags and required safety belts tend to expand the security of car drivers and travelers (in spite of the fact that not as much as though there were no increase in speed) yet diminish the security of pedestrians.

The deployment of airbag can reduce the range of injuries to a number of parts of the body.

Jogging on hard surfaces with insufficiently padded shoes produces large forces in the feet and legs.

Step2247 [10]

Answer:

Part a)

$F = 15600 N$

Part b)

force is 21.2 times more than the weight of the person

Explanation:

Part a)

As it is given that the distance after which he stopped is given as

d = 1.50 cm

here finally it stops so final speed is given as

$v_f = 0$

initial speed is given as

$v_i = 6 m/s$

now by the equation of kinematics we know that

$v_f^2 - v_i^2 = 2a d$

$0^2 - 6^2 = 2(a)(0.015)$

$a = -1200 m/s^2$

Now the force on the leg is given as

$F = ma$

m = mass of leg = 13 kg

$F = (13 kg)(-1200 m/s^2)$

$F = 15600 N$

Part b)

Force due to weight of the object

$F_g = Mg$

here we know

M = 75.0 kg

$F_g = 75(9.81)$

$F_g = 735.75 N$

Now we know that the ratio of the weight with the force on leg is given as

$\frac{F}{F_g} = \frac{15600}{735.75} = 21.2 N$

so force is 21.2 times more than the weight of the person
