Question

reading/check - understanding: a student walks 3 m east, then 3 m west, and the trip takes 6 s total. what is the average velocity? 1 m/s east 0 m/s 6 m/s 1 m/s west

Explanation:

Step1: Calculate total displacement

Displacement is net change in position. Let east be positive: $3\ \text{m} + (-3\ \text{m}) = 0\ \text{m}$

Step2: Apply average velocity formula

Average velocity = $\frac{\text{Total Displacement}}{\text{Total Time}}$
$\text{Average Velocity} = \frac{0\ \text{m}}{6\ \text{s}} = 0\ \text{m/s}$

Answer:

0 m/s
