## 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!
