Answer:
the speed of sound in this metal is 1668 m/s
Explanation:
given information:
x = 3.8 m
t = 8.80 ms = 0.0088 s
the speed of sound in the metal
v = x/Δt
to find the Δt of the metal, we have to calculate the interval time sound in the air
[tex]t_{air}[/tex] = x/[tex]v_{air}[/tex], [tex]v_{air}[/tex] = 343 m/s
so,
[tex]t_{air}[/tex] = 3.8/343 = 0.01108 s
Δt = [tex]t_{air}[/tex] - t
= 0.011079 - 0.0088
= 0.002279
v = x/Δt
= 3.8/ 0.002279
= 1668 m/s
