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.
Hector's velocity changed because his direction changed.
To determine whether Hector's velocity changed, we need to understand the difference between velocity and speed. Velocity is a vector quantity that includes both speed and direction.
In this scenario, Hector initially went due south with a speed of 3 m/s. This means his velocity had a magnitude of 3 m/s in the south direction.
Then, Hector turned west and continued at the same speed for another three blocks. Since he changed direction from south to west, his velocity vector changed as well, even though his speed remained constant. Now, Hector's velocity has a magnitude of 3 m/s in the west direction.
Therefore, the correct answer is: Hector's velocity changed because his direction changed.
