A 1.6kg box moves back and forth on a horizontal frictionless surface between two different springs, as shown in the accompanying figure. The box is initially pressed against the stronger spring, compressing it 4.1cm , and then is released from rest
A.)By how much will the box compress the weaker spring?
B.)What is the maximum speed the box will reach?
