does it make since if it takes 675 food Calories to lift me up 17 ft(adsbygoogle = window.adsbygoogle || []).push({});

look below

*IGNORING HORIZONTAL DISTANCE*

i gotta figure out how much work is done to get myself up from my class to the cafeteria which is 17 ft in vertical hieght

PE=mgh

my weight is 120 lbs i converted to mass

54.545 Kg which makes 54,545 g

multiply that by gravity 10 (yes i know 9.8 but my teacher is stupid and confusing)

then multiply that by hieght which is 17 ft but its got to be Meters so i did 5.1816

so i get Work = 2,826,303.72 Joules

got to convert that to FOOD Cal and i got around 675

with this conversion

J * (1 cal/4.187J) * (1 Food Cal/1,000cal) = Food Calories

so does that makes since it takes 675 food Calories to lift me up 17 ft
