1. The problem statement, all variables and given/known data If a fish is attached to a vertical spring and slowly lowered to its equilibrium position, it is found to stretch the spring by an amount d. If the same fish is attached to the end of the unstretched spring and then allowed to fall from rest, through what maximum distance does it stretch the spring? (Hint: Calculate the force constant of the spring in terms of the distance d and the mass m of the fish.) 2. Relevant equations F=-kx 3. The attempt at a solution I do not remember my prof doing anything like this in class. Can anyone help?
