Two springs, with force constants k1=175N/m and k2=270N/m, are connected in series, as shown in (Figure 1) .

Question

Part A: When a mass m=0.50kg is attached to the springs, what is the amount of stretch, x?

k1
I
k2
I
m
? ]
x

Answer 1

the force is the same in each so add the extensions:

mg/k1 + mg/k2
