A block of mass m is attached to the end of a horizontal massless spring (spring con- stant k), resting on a frictionless table. The mass is then given an initial displacement xo from equilibrium, and an initial speed vo. Ignoring friction, use energy methods to find (a) its maximum speed, and (b) its maximum stretch from equilibrium, in terms of the given quantities.
