One end of a light spring of spring constant k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacement, the work done by the spring is (1)/(2) kx^(2). The possible cases are (a) The spring was initially compressed by a distance x and was finally in its natural length (b) it was initially steched by a distance x and finally was in its natural length (c ) it was initially in its natural length adn finally in a compressed position. (d) it wasinitially in its natural length and finally in a stretched position.

1.	One end of a light spring of spring constant k is fixed to a wall and the other end is tied to a block placed on a smooth horizontal surface. In a displacement, the work done by the spring is (1)/(2) kx^(2). The possible cases are (a) The spring was initially compressed by a distance x and was finally in its natural length (b) it was initially steched by a distance x and finally was in its natural length (c ) it was initially in its natural length adn finally in a compressed position. (d) it wasinitially in its natural length and finally in a stretched position.
