Vector Diagram for Homework - Assistance and Solution
In summary, the conversation is about a person asking for help with a vector diagram and part c of a problem. They are specifically asking for help with using conservation of energy and determining the condition for two vectors to be perpendicular to each other. They also mention the use of Pythagorean theorem but are unsure of its relevance.

well:
0.5*m*u2 = 0.5*m*v12 + 0.5*m*v22
but how does this prove anything in relation to the diagram?

Well, that's the condition for conservation of momentum. It's not a direct proof that the paths are perpendicular to each other. A direct proof of that is to take the inner product (or dot product, depending on what you call it) of the two final momentum vectors, and ensure that the result is zero (that is the definition of perpendicular vectors).

well i have given you all the information I have
apparently it has something to do with Pythagrous but no idea what?
FAQ: Vector Diagram for Homework - Assistance and Solution
What is a vector diagram?
A vector diagram is a graphical representation of a vector, which is a quantity that has both magnitude (size) and direction. It is commonly used in physics, engineering, and mathematics to visually represent forces, velocities, and other physical quantities.
Why are vector diagrams important for homework?
Vector diagrams are important for homework because they help students understand and visualize complex mathematical and scientific concepts. They also allow students to accurately solve problems by using graphical methods, which can be more intuitive and efficient than algebraic methods.
How do I create a vector diagram for my homework?
To create a vector diagram, you will need to know the magnitude and direction of the vectors involved. You can then use a ruler and protractor to draw the vectors to scale on a piece of graph paper. Alternatively, you can use vector drawing software or online tools to create a digital vector diagram.
What are some common mistakes to avoid when creating a vector diagram for homework?
Some common mistakes to avoid when creating a vector diagram include not accurately representing the magnitude and direction of the vectors, not using the correct scale, and not clearly labeling the vectors and their components. It is also important to double-check your calculations and ensure that the vector diagram accurately reflects the solution to the problem.
Can I use a vector diagram to solve any type of problem?
Vector diagrams are useful for solving problems involving vectors, such as finding the resultant of two or more vectors or determining the components of a vector. However, they may not be applicable for all types of problems, such as those involving scalar quantities. It is important to understand the concepts and principles behind vector diagrams to determine when and how they can be used to solve a problem.
