A silicon micro-cantilever with an effective spring constant k k\,k is loaded with a micro-particle of mass mmm. The cantilever is deflected from its equilibrium position by an initial displacement s s\,s and released from rest, causing it to undergo simple harmonic motion with a maximum kinetic energy EEE.
The mass of the micro-particle is then quadrupled to 4m (keeping the cantilever stiffness k k\,k the same), and the cantilever is released from rest with an initial displacement of 0.5s.
What is the new maximum kinetic energy of the system?
