Let's denote the length of the spring when no weights are attached as "l".
From the given information, we can set up a proportion between the length of the spring and the weight attached to it:
(length with weight)/(weight) = (length without weight)/(0)
Using the given values, we set up the proportion:
(12 inches)/(2 pounds) = (l)/(0)
Simplifying the proportion:
(12/2) = l/0
6 = l/0
Since dividing by zero is undefined, we cannot determine the value of "l" using this method.
A spring has a length of 12 inches when a 2-pound weight is attached, and a length of 18 inches when a 5-pound weight is attached. Use rate of change to find the length of the spring when no weights are attached.
