For a system shown in the figure the block has mass 1.5 kg & spring constant 8.0 N/m.Suppose the block is pulled down a distance 12 c.m & released.If the friction of force is given by -bv where b=0.23 kg/s.find the number of oscillation made by the block during the time interval required for amplitude to fall to 1/3 of initial value

ω0=mk−(2mb)2
F∽A2
If amplitude gets reduced to one third the force will reduce to one nineth.
