During an auto accident, the vehicle's airbags deploy and slow down the passengers more gently than if they had hit the windshie
NemiM [27]

Answer:

0.38 m

Explanation:

As we know that the person due to the airbag action, comes to a complete stop, in a time of 36 msec or less, and during this interval, is decelerated at a constant rate of 60 g, we can find the initial velocity (when airbag starts to work), as follows:

vf = v₀ -a*t  

If vf = 0, we can solve for v₀:

v₀ = a*t = 60*9.8 m/s²*36*10⁻³s = 21.2 m/s

With these values of v₀, a and t, we can find Δx, applying any kinematic equation that relates these parameters with the displacement.

Just for simplicity, we can use the following equation:

 vf^{2} - vo^{2} =2*a*d

where vf=0, v₀ =21.2 m/s and a= -588 m/s².

Solving for d:

 d =\frac{21.2 m/s}{588 m/s2} = 0.38 m

⇒ d = 0.38 m

At 45 degrees s latitude, the angle of the noon sun is lowest and the length of daylight is shortest on:
Marat540 [252]

Answer;

- June 21

At 45 degrees latitude, the angle of the noon sun is lowest and the length of daylight is shortest on June 21.

Explanation;

-On June 21 you will note that the Northern Hemisphere is pitched toward the Sun. This means that the Sun's vertical ray is striking the Earth at the Tropic of Cancer (23.5 degrees N).

-Days tend to get longer in the northern hemisphere from December 21 to June 21, and then grow shorter from June 21 to December 21.  The June solstice is the summer solstice in the Northern Hemisphere and the winter solstice in the Southern Hemisphere. The date varies between June 20 and June 22, depending on the year, and the local time zone.

Does the speedometer of a car measure speed or velocity? Explain.
deff fn [24]
Car speedometer only measures speed and doesn't give any information about direction. So yes to speed, no to velocity. ... Therefore the object CANNOT have a varying speed if its velocity is constant.
