To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by
Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And
Therefore using the values given we can find the velocity through,
Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1
Therefore the cars goes to 145.3m/s
Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:
Now, for the average velocity of the girl we can use the following formula:
where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
