If we assume a typical efficiency for the body, as quoted in the video, how much energy input would it take to climb a ladder, i
1 answer:
The energy input would it take to climb a ladder will be 20000 J.
<h3>What is the mechanical advantage?</h3>Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtain the efficiency of the given mechanical machine.
Mechanical advantage is a measure of how much a machine multiplies the input force.
The complete question is;
"if we assume a typical efficiency of 25% for the human body how much energy input would it take to climb a ladder increasing body potential energy by 5000J"
The formula for the efficiency is;
Hence, the energy input would it take to climb a ladder will be 20000 J.

<h3>What is the free body diagram?</h3>Free-body diagrams are utilized to display the relative direction and strength of all forces that are being applied to an item in a certain scenario. A unique illustration of the geometric diagrams that were covered in a previous lesson is the free-body diagram. We will make use of these graphics throughout the entire study of physics.
