06.49: Three identical Hookian wto4b.uv)* / wonh+i,uoo8vjxa - ya3 springs of spring c3dpwh gx7we6ew1 -n2 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 oscillation. Assume tha 7eg1n6cx hw3w2p -wedt the horizontal platform does not rotate during the oscillations.What is the period of the oscillation?
