In a pickup game of dorm shuffleboard, students crazed by final exams use a broom to propel a calculus book along the dorm hallway. If the 2.4 kg book is pushed from rest through a distance of 0.74 m by the horizontal 18 N force from the broom and then has a speed of 2.0 m/s, what is the coefficient of kinetic friction between the book and floor?
