Consider the velocity vs. time graph shown here. focusing on the issue of whether the object turns around (reverese direction) Velocity | | (TRIANGLE HERE)___time a. why might a smart student say the object reverse direction? b. why might a smart student say the object doesn't reverse direction? c. does the object reverse direction? as part of your explanation, explain why the other argument is incorrect, and give advice to someone who made that mistake that can help them understand why they made the mistake and how they can avoid it in the future.
