Use hookes law a force of 265 newtons stretches a spring 0.15 meters a) what force stretches the spring 0.2 b)how far does a force of 140 newton’s stretch the spring

we know that

Hooke's law

where

F is force

k is spring constant

x is stretched length

we are given F=265N and x=0.15m

now, we can use it and find k

we get

now, we can plug back

(A)

we are given

stretches the spring 0.2

so, x=0.2

and then we can find F

(B)

we are given

F=140N

so, we can set it equal and then we can solve for x

............Answer

2x + 8
