  The Potential Energy of the paricle is 5 Joules at the mean pos.(With Reference to an arbitary Refrence Point).
  
  With Reference to same arbitary Refrence Point , the total energy of the particle is 9 Joules.
  
  So the Kinetic Energies at the mean pos. = 9J -5J = 4 Joules
  
  At the amplitude the all the kinetic energy will convert into spring potential energy
  
  4 Joules = (1/2)kx2 = (1/2)*k(0.01)2
  
  k = 8*10
  
  Time Period is 2pi (m/k)1/2= 2pi (2/8*104)1/2 = 2pi(0.25*10-4)1/2= 2 pi (0.5*10-2)=3.14*10-2s
