If the dot product of two non-zero vectors is exactly zero, the vectors must be:

If two non-zero vectors $\vec{A}$ and $\vec{B}$ are perfectly parallel to each other, the magnitude of their vector cross product ($\vec{A} \times \vec{B}$) will be:

An object begins with an initial velocity of 9 m/s and accelerates uniformly at 3 m/s² for 8 seconds. What is its final velocity?

An object begins with an initial velocity of 6 m/s and accelerates uniformly at 5 m/s² for 9 seconds. What is its final velocity?

An object begins with an initial velocity of 7 m/s and accelerates uniformly at 5 m/s² for 6 seconds. What is its final velocity?

An object begins with an initial velocity of 6 m/s and accelerates uniformly at 8 m/s² for 5 seconds. What is its final velocity?

An object begins with an initial velocity of 7 m/s and accelerates uniformly at 4 m/s² for 11 seconds. What is its final velocity?
