An object of mass 2.0 kg is attached to a spring that has a spring constant of 62 N/m. Suppose the spring is stretched a maximum distance of 0.15 m before the object starts to move. What is mu_s, the coefficient of static friction

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

ingenuity says that the answer is 2.7 m.
