A 240 gram block slides back and forth on a frictionless surface between two springs. The left- hand spring has 140 N/m and its maximum compression is 15 centimeter. The right hand spring has 260 N/m.
A) Determine maximum compression of the right-hand spring.
B) Determine the speed of the block as it moves between the springs.
