Homework Statement
Draw a free body diagram showing all the forces on the elastic band, and a free body diagram showing all the forces on the bag of coins
Homework Equations
F=-kx
F=mg
The Attempt at a Solution
I drew the forces on the elastic band as T = mg (m = mass of coins since the elastic band's mass isn't stated) upwards
and mg downwards
The forces I drew on the bag were F = kx upwards (the force of the elastic's stretch pulling proportionally upwards on the bag) and F = mg downwards (m = mass of coins)
If it were a rope attaching the bag to the ceiling I'd be ok but I'm a bit thrown off since it's an elastic band. Please let me know if this seems logical.
Thanks in advance for your help!
