John did the most work.
Explicación
## Step 1The problem involves calculating the work done by each person. The formula for work is given by:### **Work = Force x Distance**where the force is measured in Newtons (N) and the distance is measured in meters (m).## Step 2Calculate the work done by Sally. She lifts her cat with a force of 22 N over a distance of 0.50 m. So, the work done by Sally is:### **Work = 22 N x 0.50 m = 11 J**## Step 3Calculate the work done by Taylor. She lifts herself with a force of 500 N over a distance of 2 m. So, the work done by Taylor is:### **Work = 500 N x 2 m = 1000 J**## Step 4Calculate the work done by John. He carries a candy weighing 4,448 N over a distance of 500 m. So, the work done by John is:### **Work = 4,448 N x 500 m = 2,224,000 J**## Step 5Calculate the work done by Henry. He carries groceries weighing 40 N each over a distance of 1 m and then walks 10 m. So, the work done by Henry is:### **Work = 40 N x 1 m = 40 J**## Step 6Compare the work done by each person. The person who did the most work is the one with the highest value of work done.
