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 4.8 kg book is pushed from rest through a distance of 0.95 m by the horizontal 20 N force from the broom and then has a speed of 1.4 m/s, what is the coefficient of kinetic friction between the book and floor? Number i UnitsThe figure shows an initially stationary block of mass m on a floor. A force of magnitude 0.500mg is then applied at upward angle 0 = 20% What is the magnitude of the acceleration of the block across the floor if (a) Us = 0.600 and MK = 0.530 and (b) Is = 0.400 and HK = 0.330? (a) Number Units (b) Number i Units
