To find the average acceleration between $t = 0 \, \text{s}$ and $t = 4 \, \text{s}$, we can use the formula for average acceleration:

$a_{\text{avg}} = \frac{\Delta v}{\Delta t} = \frac{v_f - v_i}{t_f - t_i}$

Where:

• $v_f$ = final velocity at $t = 4 \, \text{s}$,
• $v_i$ = initial velocity at $t = 0 \, \text{s}$,
• $t_f$ = final time ($4 \, \text{s}$),
• $t_i$ = initial time ($0 \, \text{s}$).

If you provide the initial velocity ($v_i$) and the final velocity ($v_f$), I can calculate the exact result. Could you share the values (or upload the graph/table)?

Let me know if this explanation was helpful or you need further assistance!

Meanwhile, here are 5 related questions to consider:

1. What is the relationship between velocity and acceleration over time?
2. How does constant acceleration differ from average acceleration?
3. If velocity is graphed, how can you use the slope to find acceleration?
4. What is the significance of negative acceleration (deceleration)?
5. How does acceleration relate to force and mass (Newton's Second Law)?

Tip: Always double-check units when calculating acceleration to ensure consistency!
