A small block A of mass 2 kg is attached to a spring of force constant 1200 Nm ⁻¹ , and rests on a smooth horizontal surface at x=0 as shown in figure. A second block B of mass 1 kg slides along the surface towards A at 6 ~ms ⁻¹ and sticks to it. Assuming that the collision occurs at t=0 , position x (in meter) of block A as a function of time t is expressed as
