In a pickup game of dorm shuffleboard, students crazed by final exams use a broom to propel a calculus book to the right along the dorm hallway. If the 3.50 kg book is pushed from rest through a distance of 0.900 m by the horizontal 25.0 N force from the broom and then has a speed of 1.60 m/s, what is the coefficient of kinetic friction between the book and the floor?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
