does it make since if it takes 675 food Calories to lift me up 17 ft
look below
*IGNORING HORIZONTAL DISTANCE*
i got to 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
