Question

If the length of a `26 cm` spring increases to `58 cm` when a `4 kg` weight is hanging from it, what is the spring's constant?

Answer 1

`k=122,63 N/m`

Explanation:

`x_1=26 cm`
`x_2=58 cm`
`Delta x=32cm=0,32 m`

`F=G=m*g=4*9,81=39,24 N`

`F=k*Delta x`
`39,24=k*0,32`

`k=(39,24)/(0,32)`

`k=122,63 N/m`
