Pulling a banner behind itself, an airplane exerts a force of 120 newtons over a distance of 550 km Calculate the work the airplane does on the banner. Work (W) is the product of the force and the system's dispacement. 21% Joules 66,000 Joules 4.58 Joules

## Step 1<br />The problem involves calculating the work done by an airplane on a banner. The formula for work is given by:<br />### **Work (W) = Force (F) x Displacement (d)**<br />In this formula, the force is measured in Newtons (N) and the displacement is measured in meters (m).<br /><br />## Step 2<br />The force exerted by the airplane is given as 120 Newtons and the displacement is 550 kilometers. However, the displacement needs to be in meters for the formula to work correctly. Therefore, we need to convert kilometers to meters by multiplying by 1000.<br /><br />## Step 3<br />After converting the displacement to meters, we multiply the force by the displacement to get the work done.
