A spring-block system is resting on a frictionless floor as
shown in the figure. The spring constant is 2.0 Nm-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
ms- 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
