question 4 of 5 view policies current attempt in progress how is the direction of the average acceleration determined? the direction of the average acceleration is the same as that of the average velocity vector. the direction of the average acceleration is that of the vector addition of the initial velocity from the final velocity. the direction of the average acceleration is the same as that of the instantaneous velocity vector. the direction of the average acceleration is that of the vector subtraction of the initial velocity from the final velocity. the direction of the average acceleration is the same as that of the displacement vector.

Answer

Brief Explanations:

Average acceleration $\vec{a}_{avg}=\frac{\vec{v}_f - \vec{v}_i}{\Delta t}$, where $\vec{v}_f$ is final - velocity and $\vec{v}_i$ is initial - velocity. The direction of average acceleration is the same as the direction of the vector $\vec{v}_f-\vec{v}_i$, which is the vector subtraction of the initial velocity from the final velocity.

Answer:

The direction of the average acceleration is that of the vector subtraction of the initial velocity from the final velocity.
