A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the table and the box, thus when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.80 kg, and the spring has a spring constant of 56 N/m. The coefficient of static friction among the table and box on which it rests is μs = 0.54. How far can the springs best retched from its unstrained position without the box moving when it is released?
