Final answer:
To use a formula to solve a problem, identify and write down the equation, list the knowns and unknowns, ensure proper units, plug in numbers and units, calculate the answer, and check the solution for reasonableness.
Step-by-step explanation:
Steps for Using a Formula to Solve a Problem
To solve a problem using a formula, follow these steps in order:
Identify the equation to use based on the problem's requirements. Write the formula down.
Make a list of what is given or can be inferred from the problem as stated. This helps in identifying the knowns and the unknowns.
Make sure all values are in the correct units for the formula. If they are not, perform the necessary unit conversions.
Plug in the numbers and units into the formula.
Calculate the answer, making sure to include the correct units in your calculation to ensure accuracy.
Check your answer to ensure it is reasonable and that it makes sense given the context of the problem.
These steps should allow you to successfully solve problems that require the application of formulas by substituting known quantities, obtaining numerical solutions, and verifying the plausibility of the results.
