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 box and the table, so 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 59 n/m. the coefficient of static friction between the box and the table on which it rests is s 0.74. how far can the spring be stretched from its unstrained position without the box moving when it is released?

The answer to your question is 20.18

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
