Joe lifts a bike box from a slep that is 0.8m high to a sholl that is 1.75m How much work old Joe accomplish? a ii 43.1

## Step 1<br />The problem involves calculating the work done by Joe in lifting a box. In physics, work is defined as the product of the force applied and the distance over which the force is applied. In this case, the force is the weight of the box, which is the product of the mass of the box and the acceleration due to gravity.<br /><br />### **Work = Force x Distance**<br /><br />## Step 2<br />The weight of the box is calculated by multiplying the mass of the box (5 kg) by the acceleration due to gravity (9.8 m/s²).<br /><br />### **Weight = Mass x Gravity = 5 kg x 9.8 m/s² = 49 N**<br /><br />## Step 3<br />The distance over which the force is applied is the difference in height between the step and the shelf, which is 1.75 m - 0.8 m = 0.95 m.<br /><br />## Step 4<br />The work done by Joe is then calculated by multiplying the weight of the box by the distance over which the force is applied.<br /><br />### **Work = Weight x Distance = 49 N x 0.95 m = 46.55 J**
