A fast-food hamburger (with mozzarella cheese and bacon) includes 1000 Calories.
The Calorie here’s a kilocalorie and you will find 4.18kj in a single kcal So 1000 Cal x 4.18kj/Cal = 4180kJ
b) this may boost the possible power of an item U = m*g*y therefore y = U/(g*m) =
4180000J/(9.8m/s^2*13kg) = 32810m = 32.8km
