How Do You Calculate Total Work Done in This Physics Problem?

In summary, the conversation discusses solving a work question involving a 35-kg trunk being dragged up a ramp and then horizontally by a force of 90 N. Two methods are suggested, using force diagrams and vector sums, to find the total work done which is equal to 2114 J.

There is a work question which I am having difficulty getting.

A 35-kg trunks is dragged 10 m up a ramp inclined at an angle of 12 degrees to the horizontal by a force of 90 N applied at an angle of 20 degrees to the ramp. At the top of the ramp, the trunk is dragged horizontally another 15 m by the same force. Find the total work done. .. Answer = 2114 J

Its basically two problems in one. Draw two force diagrams, one for the ramp, and one for the horizontal drag. Balance the forces in each and then use superposition to find net force in each case. Then find the work done in each case and sum them.

or you could get USE vector sums which i believe is easier, and then u can work it out using pythagoras theorem.

FAQ: How Do You Calculate Total Work Done in This Physics Problem?

What does it mean to "work from multiple angles"?

"Working from multiple angles" refers to approaching a problem or task from different perspectives or methods. This can involve considering various variables, using different techniques, or collaborating with others to find the most effective solution.

Why is working from multiple angles important in science?

In science, working from multiple angles allows for a more comprehensive and well-rounded understanding of a topic or phenomenon. It helps to minimize bias and ensures that all factors are considered in the research process.

What are some examples of working from multiple angles in scientific research?

Examples of working from multiple angles in scientific research include using different research methods (such as experiments, surveys, and case studies), collaborating with experts from different fields, and analyzing data from various sources.

How can working from multiple angles improve the accuracy and reliability of scientific findings?

By considering different perspectives and approaches, working from multiple angles can help to identify and address potential flaws or limitations in the research process. This can lead to more accurate and reliable findings that are less likely to be influenced by bias or external factors.

Are there any challenges or limitations to working from multiple angles in science?

One challenge of working from multiple angles in science is the potential for conflicting or inconclusive results. It can also be time-consuming and require a significant amount of resources. Additionally, different perspectives and methods may not always align, leading to difficulties in synthesizing findings. However, these challenges can be overcome through careful planning and collaboration.
