Answer:
1 calorie
Step-by-step explanation:
To find this result we will need to make a calculation, but first we need to remember that the amount of calories we would spend on the activity described in the above question would be equal to the amount of work done by the force used to push the box.
Knowing this, we can start our calculation.
For convenience, let's use the letter "F" to represent the force applied to push the box (4,187 N), the letter "d" to represent the box offset (1m), and the letter "W" to represent the calories lost.
W = F x d
W = 4.187 x 1 = 4.187J
In this case, 1 calorie equals 4.1787J
W = 4.187 / 4.187 = 1 calorie.
