Now consider the same two springs in series.
6.4 N/cm, 3.6 N/cm
44 N
What distance will the spring of constant
3.6 N/cm stretch?
Answer in units of cm.

In this same series spring system, what is the
effective combined spring constant kseries of
the two springs?
Answer in units of N/cm. 
The force is the same in series.
44=F1=k1*x1
44=k2*x2
so total displacement is x1+x2
x1+x2=total= 44(1/k1+1/k2)
