Two identical springs (neglect their masses) are used to “play catch” with a small block of mass 110g (see the figure ). Spring A is attached to the floor and compressed 10.0cm with the mass on the end of it (loosely). Spring A is released from rest and mass is accelerated upward. It impacts the spring attached to the ceiling, compresses it 2.00cm, and stops after travelling a distance of 30.0cm from relaxed position of spring A to the relaxed position of spring B.
Decide the spring constant of the two springs (similar since they are identical).
