Answer:
Explanation:
We are given that
The wavelength of sound wave=
1 cm/s=
Speed of sound wave,v=
We have to find the period of the wave.
We know that
Frequency=
Using the formula
Frequency = Hz
Time period=
Using identity:
Hence, the time period of the wave=
a. The particle has velocity at time ,
so that after it will have velocity
.
b. The sign of the velocity is negative, so it's moving in the negative direction.
c. Its speed is 3.00 m/s.
d. The particle's velocity changes according to
which is positive and indicates the velocity/speed of the particle is increasing.
e. Yes. The velocity is increasing at a constant rate. Solving for is trivial; this happens when
.
f. No, the velocity is positive for all beyond 1.50 s.
