we know that

Hooke's law

F=kx

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

265=k*0.15

we get

k=\frac{5300}{3}

now, we can plug back

F=\frac{5300}{3}x

(A)

we are given

stretches the spring 0.2

so, x=0.2

and then we can find F

F=\frac{5300}{3}*0.2

F=353.333N

(B)

we are given

F=140N

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

140=\frac{5300}{3}*x

x=0.07925m............Answer

What is the solution of the equation (x – 5)2 + 3(x – 5) + 9 = 0? Use u substitution and the quadratic formula to solve.
Vitek1552 [10]
(X-5)2+3(X-5)+9 = 0
let expand the equation
(x)x2-(5)x2 + 3(x)-3(5) + 9 = 0
2x-10+3x-15+9=0
collect like terms
2x+3x-10-15+9 =0
5x-10-6 =0
5x-16=0
5x=0+16
5x=16
divide both side by 5 we have
x=16/5
