The speed of the moving train is 2.31 m/s
What is called speed?
Speed is described as. the rate at which an object's position changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it only has a direction and no magnitude.
Speed is calculated as follows: speed = distance/time. Knowing the units for distance and time is necessary to calculate the units for speed.
According to the given information:
[tex]f=\frac{v}{s} *f_{0}[/tex]
s = speed in air,
v is the speed of the train,
f₀ is the frequency of the siren,
f₀ = 516 Hzs = 340.29 m/s
f = 3.5 Hz
v = (3.5 / 516) × 340.29 = 2.31 m/s.
So, the speed of the moving train is 2.31 m/s
