A 3 kg textbook is forced against a horizontal spring of negligible mass andforce constant of 230 N/s, compressing the spring by 0.25 m. When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction0.35. Use the work-energy theorem to find how far the textbook moves from itsinitial position before coming to rest.
