Question

Answer 2

so if that other formula doesn't work for this one then i have one more we learned

Answer 3

it's like that other one right?
so W = integral from (smaller ft) to (bigger ft) of (equation) dx

Answer 4

k wait

Answer 5

15?

Answer 6

that's what I got but I'm debating with myself of whether or not compressing it would mean the length would be negative? :/

Answer 7

:o

Answer 8

15

Answer 9

yeah :P that'd be it
