Answer:

Average speed of the car is 36.36 miles per hour

Explanation:

It is given that,

Total distance traveled by the car, d = 200 miles

Total time taken, t = 5.5 hours

In this case, we have to find the average speed of the car. Average speed of the car is defined as the total distance divided by total time taken. Mathematically, it can be written as :

s=\dfrac{d}{t}

s=\dfrac{200\ miles}{5.5\ hours}    

s = 36.36 miles per hour

Hence, the average speed of the car is 36.36 miles per hour.

36 miles per hour becuase if you do 200 divied by the hours your get 36 which is the speed

A train whistle is heard at 300 Hz as the train approaches town. The train cuts its speed in half as it nears the station, and t
givi [52]

To solve this problem we will apply the concepts related to the Doppler effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other. Mathematically it can be described as,

f = f_0 (\frac{v_0}{v_0-v})

Here,

f_0 = Frequency of Source

v_s = Speed of sound

f = Frequency heard before slowing down

f' = Frequency heard after slowing down

v  = Speed of the train before slowing down

So if the speed of the train after slowing down will be v/2, we can do a system equation of 2x2 at the two moments, then,

The first equation is,

f = f_0 (\frac{v_0}{v_0-v})

300 = f_0 (\frac{343}{343-v})

(300*343) - 300v = 343f_0

Now the second expression will be,

f' = f_0 (\frac{v_0}{v_0-v/2})

290 = (343)(\frac{v_0}{343-v/2})

290*343-145v = 343f_0

Dividing the two expression we have,

\frac{(300*343) - 300v}{290*343-145v} = 1

Solving for v, we have,

v = 22.12m/s

Therefore the speed of the train before and after slowing down is 22.12m/s
