If the length of a #78 cm# spring increases to #108 cm# when a #6 kg# weight is hanging from it, what is the spring's constant?
Given: a spring stretches from 78 cm to 108 cm when a weight of 6 kg is place on it. What is
The key to this problem is to make sure the units are correct. Force is measured in Newtons (N).
This means we need units of
Find distance stretched in meters:
Find the force exerted on the spring:
