A backpack full of books weighing 51.4 N rests on a table in a physics laboratory classroom. A spring with a force constant of 146 N/m is attached to the backpack and pulled horizontally, as shown in the figure below. If this backpack begins to slide when the spring stretches by 2.43 cm, what is the coefficient of static friction between the backpack and the table?
