Question
An object is traveling north at a velocity of 2 m/s. Three minutes later, it is traveling east at a velocity of 2 m/s. Which of the following is true? Select all that apply.
The object must have experienced an acceleration with a component directed north at some point in those three minutes.
The object must have experienced an acceleration with a component directed east at some point in those three minutes.
The object must have experienced an acceleration with a component directed south at some point in those three minutes.
The object must have experienced an acceleration with a component directed west at some point in those three minutes.
Since the velocity of the object didn't change, it experienced no acceleration in those three minutes.
Explanation / Answer
Answer:
Since the velocity of the object didn't change, it experienced no acceleration in those three minutes, because acceleration is the rate of change of velocity.
