Homework Help: Phisics

Two identical springs (neglect their masses) are used to “play catch” with a small block of mass 200 g (see the figure).

Spring A is attached to the floor and compressed 10.0 cm with the mass on the end of it (loosely).

Spring A is released from rest and the mass is accelerated upward. It impacts the spring attached to the ceiling, compresses it 2.00 cm, and stops after traveling a distance of 30.0 cm from the relaxed position of spring A to the relaxed position of spring B as shown.
