A 2.50-kg textbook is forced against a horizontal spring of negligible mass and force constant 250 N/m, compressing the spring a distance of 0.250 m. When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction uK= 0.30. Use the work-energy theorem to find out how far the textbook moves from its initial position before coming to rest.
