Question

on a track - field, each lap is 400 meters. what is your average velocity if you run 2 laps in 200 seconds, ending up where you started? 0 m/s 100 m/s 1 m/s 4 m/s

Explanation:

Step1: Recall velocity formula

Velocity $v=\frac{\Delta x}{t}$, where $\Delta x$ is displacement and $t$ is time.

Step2: Determine displacement

Running 2 laps and ending where you started, displacement $\Delta x = 0$ m (since initial and final positions are the same).

Step3: Calculate average velocity

$v=\frac{0}{200}=0$ m/s.

Answer:

0 m/s
