Question

A spring lies on a horizontal table, and the left end of thespring is attached to a wall. The other end is connected to a box.The box is pulled to the right, stretching the spring. Staticfriction exists between the box and the table, so when the springis stretched only by a small amount and the box is released, thebox does not move. The mass of the box is 0.70 kg, and the springhas a spring constant of 52 N/m. The coefficient of static frictionbetween the box and the table on which it rests iss = 0.80. How far can the spring bestretched from its unstrained position without the box moving whenit is released?
