Let's calculate the average velocity (vavg) using the given formula and values.

Given values:

delta_x1 = -2.2 # first displacement in meters t1 = 7.4 # first time in seconds delta_x2 = -11.6 # second displacement in meters t2 = 10.9 # second time in seconds

Formula for average velocity:

vavg = (delta_x1 + delta_x2) / (t1 + t2)

Calculating the average velocity and rounding to two decimal places

vavg_rounded = round(vavg, 2) vavg_roundedThe average velocity $v_{\text{avg}}$ is $-0.75 \, \text{m/s}$.

Here are some related questions you might find interesting:

1. How would the average velocity change if the time intervals were different?
2. What is the significance of a negative average velocity?
3. How would you calculate the average speed instead of velocity?
4. How does average velocity differ from instantaneous velocity?
5. Can average velocity be zero even if there is displacement?

Tip: Always pay attention to the signs of displacement values, as they indicate direction.
