Question

A spring-block system is resting on a frictionless floor as
shown in the figure. The spring constant is 2.0 N m⁻¹ and the
mass of the block is 2.0 kg. Ignore the mass of the spring.
Initially the spring is in an unstretched condition. Another
block of mass 1.0 kg moving with a speed of 2.0 m s⁻¹
collides elastically with the first block. The collision is such that
the 2.0 kg block does not hit the wall. The distance, in metres, between the two blocks when the spring
returns to its unstretched position for the first time after the collision is _________.
