A mass of 2kg attached to a spring of force constant 260 Nm-1 makes 100 oscillations. What is the time taken for 100 oscillations?

Time period of mass attached to a spring istime period=T=2πmK=23.142260=0.5509sec where m= mass attached to spring              k= force constant T=0.5509 is time taken for 1 oscillationTime taken for 100 oscillations = 0.5509 x 100 = 55.09 sec
