A spring was at its resting position where it is attached to a wall at its left side and a block at its right side as N
shown below. The spring constant is k = 95.5 – The block is moved rightwards and the spring's right end is
displaced from the position of 0.200 m to 0.220 m where it is held in place. All positions are measured from
the origin o of the wall.
