(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1) a spring has an elasticity constant of 225 newtons/meter. What is its restoring for when it's compressed of 20 centimeters ?

2) with what force must we pull a spring to pull 8 centimeters if its elasticity constant is 2 newton/cm ?

3) we suspend a weight of 4.08 kg to a spring and it pulls 8.5 cm

a) what is the elasticity constant

b) what force do you need to put to compress the spring 15 cm ?

2. Relevant equations

I honestly do not know beside Lnat, m1, L1, L2 and m2 I guess

Something with Hooke's law

3. The attempt at a solution

There's something missing for me to understand this problem :|
