Question

If the length of a `22 cm` spring increases to `55 cm` when a `7 kg` weight is hanging from it, what is the spring's constant?

Answer 1

`K=208,09" N/m`

Explanation:

`G=m*g" "G=7*9,81" "G=68,67 " "N`

`Delta x=55-22=33 cm=0,33 m`
`K:"spring constant"`
`G=K*Delta x`

`68,67=K*0,33`

`K=(68,67)/(0,33)`

`K=208,09" N/m`
