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 3.5 kg book is pushed from rest through a distance of 0.91 m by the horizontal 25 n force from the broom and then has a speed of 1.53 m/s, what is the coefficient of kinetic friction between the book and floor?

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
