Homework Statement
I'm trying to figure out the setup of an experiment I have to complete. The experiment calls for a rubber band to be secured by rods on the sides, and for a clothespin to be attached to the rubber band. I have to figure out how far back the clothespin needs to be pulled down so that it just touches the ceiling once it is let go. I have to make a force vs. displacement graph to find the work done on the rubber band and set it equal to the PE of the clothespin.
Homework Equations
I'm told that Fd (on rubber band) = GPE (clothespin).
W = Fd
The Attempt at a Solution
[/B]
Is the mass in this case the mass of the clothespin? I'm thinking that the height should be the distance from the ground to the ceiling.
Fd = 0.01 kg * 10 m/s^2 * 2.5 m
Fd = 0.25
Is my setup correct?
