), the speed of sound is
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is

Answer:
Explanation:
The elastic potential energy of a spring is given by , where
is the spring constant of the spring and
is displacement from point of equilibrium.
When released, this potential energy will be converted into kinetic energy. Kinetic energy is given by , where
is the mass of the object and
is the object's velocity.
Thus, we have:
Substituting given values, we get:
