Homework Statement
A 100g object is suspended from a spring. When 40g are added, the spring stretches an additional 5.0cm. With the total mass of 140g, the spring is set into vertical oscillations with an amplitude of 10 cm. (a) What is the force constant of the spring?
Homework Equations
[tex]\sum[/tex] F = 0 = -kx + mg
The Attempt at a Solution
From what I know, the force required to stretch a spring is not linear, so I am guessing that plugging just the 40 grams and the 5 cm into the equation won't work... What I got when I did that was k = 0.040kg * 9.8 / 0.05m = 7.84
Im guessing this is wrong?
Help would be appreciated.
