Answer 1

In physics problem-solving, the steps include identifying the knowns and unknown, selecting the appropriate equation, and substituting the known values to solve for the unknown.

Step-by-step explanation:

The student's question pertains to the process of problem-solving in physics, specifically regarding the identification and use of knowns and unknowns in solving an equation for a quantity of interest. This process involves several steps:

1. Identify the knowns: This step requires one to note all the provided information in the problem that will be used in calculations. For example, the previous text mentions velocities, such as v=0.500c and u' = c, where c represents the speed of light.
2. Identify the unknown: This step is about defining what needs to be found; in this context, it is the velocity u.
3. Choose the appropriate equation: Selecting an equation that relates the knowns to the unknown is critical in physics problem-solving.
4. Plug the knowns into the equation: After identifying the knowns and the appropriate equation, substitute the known values into the equation to solve for the unknown.

Each step is critical and should be followed systematically to ensure accurate results. In some cases, making a sketch of the situation could be very helpful in visualizing the problem.
