A 1 kg1 \mathrm{~kg} mass is attached to a spring of force constant 600 N/m600 \mathrm{~N} / \mathrm{m} and rests on a smooth horizontal surface with other end of the spring tied to wall as shown in figure. A second mass of 0.5 kg0.5 \mathrm{~kg} slides along the surface towards the first at 3 m/s3 \mathrm{~m} / \mathrm{s}. If the masses make a perfectly inelastic collision, then find amplitude and time period of oscillation of combined mass. A 1 ~kg mass is attached to a spring of force constant 600 ~N / m and rests on a smooth horizontal surface with other
