1. The problem statement, all variables and given/known data A 2.50-kg textbook is forced against a horizontal spring of negligible mass and force constant, k, of 250N/m, compressing the spring a distance of 0.250 m. When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction μk=0.30. Use the work-energy theorem to find how far the text-book moves from its initial position before coming to rest. 2. Relevant equations Wtot=K2-K1=ΔK (work-energy theorem) K=0.5mv2 3. The attempt at a solution I have no idea how to even start. It says that I have to use the work energy theorem, so all I can think of doing is substitution. However, Work-energy theorem has no reference to kinetic friction, just kinetic energy. Any ideas to get me started?
