Hi,
I'm new here, hope I am posting this question in the right place.
Ok, here is my question:
Assuming a perfect transfer of stored energy into work, how long could a 9 volt battery lift 180 pounds (81.7kg)?
Qualifier:
By "perfect transfer", I mean to assume that there is zero resistance or loss of energy. Also assumed is some sort of machine that makes perfect use of energy, lifting the weight straight up when energy comes in and dropping it straight down as soon as the energy runs out.
I can't even begin to think of how to calculate this!
Thanks,
MW
