A block of mass m is attached to the end of a spring (spring stiffness constant k ). The mass is given an initial displacement x 0 from equilibrium, and an initial speed v 0 . Ignoring friction and the mass of the spring, use energy methods to find its maximum speed. Express your answer in terms of some or all of the variables v0, k , m , and x 0 .

The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear
