(Originais Teachy 2023) - Question Very Hard of Physics

A block of mass m = 2 kg is placed on a frictionless horizontal surface and attached to an ideal spring with spring constant k = 200 N/m. The block is compressed by a distance d = 0.1 m from the equilibrium position of the spring and then released. Neglecting air resistance and considering the acceleration due to gravity g = 9.8 m/s², determine: (1) the maximum elastic force exerted by the spring on the block during the return to the equilibrium position. (2) the kinetic energy of the block when it reaches the equilibrium position of the spring. Consider that the gravitational potential energy at the equilibrium position of the spring is zero and that the elastic potential energy is given by E_p = (1/2) * k * x^2, where x is the deformation of the spring from the equilibrium position.
