06.49: Three identical Hookian springs of
t *km1ceg5t2u spring 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
125g ttum*ckeexhibits simple harmonic oscillation. Assume that the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
