On a frictionless horizotnal plane, a bob of mass m=0.1kg is attached to a spring with natural length l 0 =0.1m. The spring constant is k 1 =0.009Nm -1 when the length of the spring 1>1 0 and is k 2 =0.016Nm -1 when 1<1 0 . Initially the bob is released from l=0.15m. Assume that Hooke’s law remains valid throughout the motion. If the time period of the full oscillation is 
, then the integer closet to n is_________.
