Which formula is used to calculate average velocity? \begin{aligned} & V_{a v g}=\frac{x_{f}-x_{s}}{t_{f}-t_{s}} \\ & V_{a v g}=\frac{t_{f}-t_{s}}{x_{f}-x_{s}} \\ & V_{a v g}=\frac{d}{t} \\ & V_{a v g}=\frac{t}{d} \end{aligned}

Step 2
: Identify the Correct Formula

V_{avg} = \frac{x_{f} - x_{s}}{t_{f} - t_{s}}
To determine which formula calculates average velocity, let's analyze each option: - This formula represents displacement divided by time elapsed - Uses final and initial positions and times - Represents the standard definition of average velocity

Final Answer

The first formula, V_{avg} = \frac{x_{f} - x_{s}}{t_{f} - t_{s}}, is used to calculate average velocity.
