Three identical 9.40 masses are hung by three identical springs, as shown in the figure. Each spring has a force constant of 6.30 and was 16.0 long before any masses were attached to it. How long is each spring when hanging as shown?
(Hint: First isolate only the bottom mass. Then treat the bottom two masses as a system. Finally, treat all three masses as a system.)
Bottom Spring?
Middle spring?
Top spring?
