Answer:
7.136 m/s
Explanation:
We are given that
Mass =m=7.41 kg
Where
We have to find the speed of body when it is position
According to work energy theorem
[tex[K_f-K_i=Work\; done[/tex]
Then there would be no acceleration if the velocity of the body is 0.
I think it would be near the sun due.to high rays of sun
For a stationary siren on a firehouse is blaring at 81Hz. Assume the speed of sound to be 343m/s, the frequency perceived is mathematically given as'
F=81.721Hz
<h3>What is the
frequency perceived by a
firefighter racing toward the station at 11km/h?</h3>
Generally, the equation for the doppler effect is mathematically given as
Therefore
F=81(343+3.05556)/343
F=81.721Hz
In conclusion, the frequency is
F=81.721Hz
