Problem
A toy maker needs to know how much energy is stored in a spring that will launch a small marble. In a test, the spring is stretched uniformly from 0cm to 30cm while the pulling force rises steadily from 0N to 6N. Treat the spring as ideal for this range.
(i) Calculate the spring constant of the spring.
(ii) Determine the work done in stretching the spring from 0cm to 30cm.
(iii) If the same spring is compressed by 15cm, compute the elastic potential energy stored in it.
