SUMMARY
The discussion centers on calculating the tension T in a string within a physics problem involving forces. Key concepts include the use of the equation F = ma, and the importance of identifying forces such as gravity, tension, and friction. The coefficients of kinetic and static friction are specified as 0.15 and 0.30, respectively, which are critical for solving the problem accurately. Participants emphasize the necessity of a Free Body Diagram to visualize the forces acting on each body involved in the scenario.
PREREQUISITES- Understanding of Newton's Second Law (F = ma)
- Knowledge of Free Body Diagrams
- Familiarity with friction coefficients (kinetic and static)
- Basic trigonometry skills
- Study how to construct Free Body Diagrams for complex systems
- Learn about the implications of friction in tension calculations
- Explore advanced applications of Newton's laws in real-world scenarios
- Review examples of tension problems in physics textbooks
Students studying physics, particularly those focusing on mechanics and tension problems, as well as educators looking for examples of force analysis in classroom settings.

Start with a Free Body Diagram
The only formula you will ever need is F = ma, and some trig skills

i think the forces are gravity, tension and frictional.

What do you mean you "think" there is friction? That's actually important...

um because its touching the surface

Does the problem state there is friction? We don't want to add anything we don't want

it says " the coefficients of kinetic friction and static friction between the left hand box and the plane are .15 and .30"

Wellllllllll wouldn't that be great if you told us that from the start?
You still haven't provided us a Free Body Diagram. It's good you know what forces are present, but what forces are acting on each body?
