Two small spheres of mass 1 kg each are connected to each other by means of an unstreached spring of force constant K = 100 N/m and natural length 2.4 m . The system is placed on a smooth horizontal surface and the two spheres are given velocities v0 as shown in the figure. The maximum elongation in the spring is found to be 0.4 m during the subsequent motion. calculate v0 in m/s . Take root 31 = 5.6
