Unit B Module 1, Lesson 5: Solving Net Force Problems Lesson 2 of this assignment is worth 27 marks. The value of each question is noted in the left margin in parentheses. Remember: all net force problems should include a free-body diagram and specify positive and negative directions. . 3. A textbook with a mass of 2.18 kg is pulled across a table with a horizontal force of 5.5 N [E]. If the table has a coefficient of friction of 0.15, what is the acceleration of the textbook?
