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

The standard unit for mass is kilograms. Your answer is 1000 times too big because you converted kilograms to grams.

 

[Pengwuino]

mass is in kilograms
