To calculate the magnitude of the average acceleration vector $|\vec{a}_{avg}|$, you can follow these steps based on the given formula:

$\vec{a}_{avg} = \frac{\vec{v}_f - \vec{v}_i}{\Delta t}$

Where:

• $\vec{v}_f$ is the final velocity vector.
• $\vec{v}_i$ is the initial velocity vector.
• $\Delta t$ is the time interval over which the velocity changes.

Since the magnitude of the velocity vector doesn't change, but the direction does, you are effectively calculating the change in direction of the velocity vector.

1. Calculate the change in velocity vectors: This requires breaking the velocities into components (if necessary) and applying the Pythagorean theorem to find the magnitude of the resultant vector (change in direction).

2. Apply the Pythagorean theorem: If the velocity vectors $\vec{v}_f$ and $\vec{v}_i$ are known, the magnitude of the change in velocity $|\vec{v}_f - \vec{v}_i|$ can be found by:

$|\vec{v}_f - \vec{v}_i| = \sqrt{(v_{fx} - v_{ix})^2 + (v_{fy} - v_{iy})^2}$

3. Divide by the time interval $\Delta t$: After finding the magnitude of the change in velocity, divide by $\Delta t$ to get the average acceleration.

If you have specific values for $\vec{v}_f$, $\vec{v}_i$, and $\Delta t$, I can help you calculate this more precisely. Please provide those values if needed.

Do you want to proceed with this, or do you need more clarification?

Here are 5 related questions to consider:

1. What are the initial and final velocities $\vec{v}_i$ and $\vec{v}_f$?
2. What is the time interval $\Delta t$ over which the velocity changes?
3. Are the velocity vectors in two dimensions or three dimensions?
4. How does the direction change affect the calculation of the acceleration magnitude?
5. What role does the Pythagorean theorem play in vector magnitude calculations?

Tip: Always break velocity vectors into components before applying the Pythagorean theorem for precision.
