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 3.8 kg book is pushed from rest through a distance of 0.62 m by the horizontal 22 N force from the broom and then has a speed of 1.9 m/s, what is the coefficient of kinetic friction between the book and floor?
