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:
