Hey BALTHAZAR, good to see you again. Step 1: Calculate the total mass of the cement bags. The total mass (M) is the number of bags multiplied by the mass of each bag. M = 10 bags × 10 kg/bag = 100 kg Step 2: Calculate the force required to carry the bags. The force (F) needed to carry the bags is equal to their weight. We use the acceleration due to gravity (g ≈ 9.81 m/s^2). F = M × g F = 100 kg × 9.81 m/s^2 = 981 N Step 3: Calculate the work done. Work done (W) is given by the formula Force × Distance. W = F × Distance W = 981 N × 10 m = 9810 J Step 4: Convert the work done from Joules to calories. We know that 1 calorie = 4.184 Joules. W_calories = 9810 J4.184 J/calorie W_calories ≈ 2344.646 calories Step 5: Convert calories to kilocalories (Kcals). We know that 1 Kcal = 1000 calories. W_Kcals = 2344.646 calories1000 calories/Kcal W_Kcals ≈ 2.3446 Kcals The energy needed to transport the bags is approximately 2.34 Kcals. Send me the next one 📸
