A block of mass \(M\) is attached to a horizontal ideal spring of spring constant \(k\) and oscillates in simple harmonic motion on a frictionless horizontal surface with amplitude \(A_0\) and maximum kinetic energy \(K_{\text{max}, 0}\). At the exact instant the block reaches its maximum positive displacement \(x = +A_0\), a small lump of clay of mass \(m\) is dropped vertically from rest onto the block and immediately sticks to it. How do the amplitude and the maximum kinetic energy of the subsequent simple harmonic motion of the combined system compare to \(A_0\) and \(K_{\text{max}, 0}\), respectively?
