Hello!
The velocity function is:

a) 2.3 s earlier, we can make
t = -2.3 s, in relation to our initial time:

b) Now we can make
t = 2.3 s:

Answer:
D. The frequency is not affected as the volume of sound increases
Explanation:
Volume of the sound is defined by the amplitude of the wave or how loud a sound is whereas Frequency is basically the pitch of the sound and is inversely proportional to the wavelength . Increasing frequency will increase the pitch of the sound without affecting it's volume.
Distance = (1/2) (acceleration) (time)²
1.4m = (0.835 m/s²) (time)²
(time)² = (1.4/0.835) s²
<em>time = 1.295 s</em>
