**Question:**Which of the following situations is impossible?- **A.** An object has velocity directed east and acceleration directed west.- **B.** An object has velocity directed east and acceleration directed east.- **C.** An object has constant non-zero velocity and changing acceleration.- **D.** An object has zero velocity but non-zero acceleration.- **E.** An object has constant non-zero acceleration and changing velocity.**Explanation:**This multiple-choice question tests your understanding of the relationship between velocity and acceleration in physics. Consider how acceleration affects an object's velocity over time and which situations are physically feasible.
