physics concepts used needs to be listed

initial equations used needs to be listed

Please provide a good symbol answer/ algebra work with no numbers, this is the most important part. (I have provided an example from a past problem of what a symbolic answer is).

Units check of the symbolic answer

lastly the numerical answer is used to find the answer by plugging numbers into the symbolic answer.

Stacy has a hollow can with an air tight plunger in the open end that can slide in and out without friction. The inside has a compressed spring that presses on the plunger outward, and Representation: 0 1 2 there is a vacuum on the inside of the can.
