06.49: Three identical Hookian springs of sprin
dt+ ,sph 8gyn5g constant k are connected as shown to a mass M in equilibrium. The horizontal platform shown between the springs and the springs themselves have no mass. If the mass M is slightly displaced vertically, the mass exhibits simple harmonic
,85dynh+t g ps oscillation. Assume that the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
