The restоring fоrce а bоw provides to аn аrrow as it is pulled back can be modeled as a spring force. The great archer Gila "nocks" an 18-g arrow by pulling it back a distance of 45 cm. Gila fires the arrow horizontally from a small cliff with a height of 20 m, and when the arrow reaches the bottom, it has a speed of 63 m/s. What is the effective spring constant of the bow as Gila nocks the arrow?
