What Is the Total Stretch When Two Springs Are Combined?

[srebman]

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,

If two such springs

implies that the spring constants are the same.

Each spring experiences the same force since they are colinear.

 

[srebman]

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.
