3.(Exercise) A (massless) spring compressed a distance of 12 cm from equilibrium and of \( k=87\mathrm{~N}/\mathrm{m}\). The spring launches a Narwhal toy of mass 72 grams directly upward. What is the maximum distance above the spring's equilibrium position that the Narwhal achieves? (Like all conservation questions, make sure that you draw a before and after picture when solving this one.)
