US-2 A spring has a force constant K=12.5N/m. a) Find the energy stored in the spring if it is stretched x₂-0.150m from its unloaded length. b) Find the energy stored in the spring if it is stretched x₁-0.300m from its unloaded length. c) Find U₁U₁, the ratio of the energies you found in parts a) and b). d) The ratio x/x₁ is 2/1. Why is this not the same as your answer for part c)?
