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 un-stretched 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.)
Solution to 72P Step 1 Mass of the fish =m Spring constant =k Distance the spring is stretched =d Distance the fish is allowed to fall =y
