Hector went to the music store by heading due south at 3 m/s, then turning West and continuing at the same speed for another three blocks. Which of the following is true about Hector's velocity?(1 point)
Responses
Hector's velocity did not change because his speed did not change.
Hector's velocity did not change because his speed did not change.
Hector's velocity did not change because his direction did not change.
Hector's velocity did not change because his direction did not change.
Hector's velocity changed because his speed changed.
Hector's velocity changed because his speed changed.
Hector's velocity changed because his direction changed.
Hector's velocity changed because his direction changed.
The correct response is: Hector's velocity changed because his direction changed.
The correct answer is:
Hector's velocity changed because his direction changed.
Explanation:
Velocity is a vector quantity that includes both magnitude (speed) and direction. In this scenario, Hector initially moves due south, and then he turns west. Since the direction changes from south to west, his velocity must change as well. No mention is made about his speed changing, so we cannot conclude that his velocity changed due to a change in speed. The change in direction alone is sufficient to confirm that his velocity changed.
The correct answer is: Hector's velocity changed because his direction changed.
While Hector's speed remained constant at 3 m/s, his velocity changed because he initially moved due south and then turned west. Velocity is a vector quantity that takes into account both speed and direction.
