Answer:
10 m/s
Explanation:
The speed of a wave is given by
[tex]v=\lambda f[/tex]
where
[tex]\lambda[/tex] is the wavelength
f is the frequency
For the wave in this problem,
- The frequency is given by the number of oscillations per second, so
[tex]f=\frac{2 cycles}{1 s}=2 Hz[/tex]
- The wavelength is
[tex]\lambda=5 m[/tex]
So, the wave speed is
[tex]v=(5 m)(2 Hz)=10 m/s[/tex]
