    Answer:

    the potential energy is zero, and the kinetic energy must be maximum

        F = 0

    Explanation:

    In this exercise you are asked to complete the sentences of a simple harmonic movement of a mass-spring system.

    In this system mechanical energy is conserved

    at the most extreme point the carousel potential energy is

              K_e = ½ k x²

    the kinetic energy is zero for that stopped.

    At the equilibrium point

    the spring elongation is x = 0 so the potential energy is zero

    and the kinetic energy must be maximum since total energy of the system is conserved

    the spring force is

                 F =- k x

    as in the equilibrium position x = 0 this implies that the force is also zero

                 F = 0
