Answer
The work done by the girl in climbing up the rope is 2500 J.
Explanation
## Step1In physics, the work done by a force on an object is calculated when the force is exerted over a distance and results in displacement of the object. In this case, the girl's weight (which is equivalent to the force due to gravity) causes her to climb up the rope, which is a movement against the gravitational force.## Step2The formula to calculate work done is:### **Work done (W) = Force (F) x Distance (d)**## Step3In this problem, the force (F) is the girl's weight, which is 500 N, and the distance (d) is the height she climbs, which is 5.0 m.## Step4Substitute the given values into the formula:### **W = 500 N x 5.0 m**## Step5Calculate the above expression to get the work done.
