A certain spring has a resting length of 0.08 m (8 cm) when it is not stretched. The spring is stretched to a length of 0.10 m (10 cm), 0.02 m beyond its natural length. Holding it in this stretched position requires a force of 20 N. Question: What is the force function for this spring? Hooke's Law says that the force required to maintain the spring in a stretched position is the linear function F(x) = kx. Find the spring constant, k, for the spring described above, and enter that number as your final answer.
