Answer:

2.33651226158 m

Explanation:

From the question the required data is as follows

f = Frequency of the initial note = 146.8 Hz

v = Velocity of sound in air = 343 m/s

The wavelength of a wave is given by

$\lambda=\dfrac{v}{f}$

$\Rightarrow \lambda=\dfrac{343}{146.8}$

$\Rightarrow \lambda=2.33651226158\ m$

The wavelength of the initial note is 2.33651226158 m

bulgar [2K]

Answer:

KE = 32,000J

v = 8m/s

Explanation:

KE = .5*m*v²

KE = .5*4000kg*(4m/s)²

KE = 32,000J

32,000J = .5*1000kg*v²

v² = 64

v = 8m/s
