Explanation:
It is given that,
Frequency of the object, [tex]f_o=493\ Hz[/tex]
Frequency of another object, f = 1433 Hz
Let [tex]v_s=340\ m/s[/tex] is the speed of sound and v is the speed of the train. The speed of the train can be calculated using Doppler's effect as :
[tex]f=\dfrac{v_s}{v_s-v}\times f_o[/tex]
[tex]v=v_s-\dfrac{f_ov_s}{f}[/tex]
[tex]v=340-\dfrac{493\times 340}{1433}[/tex]
v = 223.02 m/s
So, the speed of the train is 223.02 m/s. Hence, this is the required solution.
