Homework Help: Attaching two springs together

  1. May 4, 2006 #1
    I have a question on a recent assignment.

    A weightless spring is stretched 10 cm by a suspended 1-kg block. If two such springs are used to suspend the block, one spring above the other, to effectively provide one double-length spring, then the total stretch of the double-length spring will be? Is the k constant the same in both cases?

    Thank You,

    implies that the spring constants are the same.

    Each spring experiences the same force since they are colinear.

    If each spring experiences the same force, 1-kg, then each will have a 10 cm strech and total 20 cm combined?

    Yes, that's correct.
