Question 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 changed because his direction changed. Hector's velocity changed because his direction changed. Hector's velocity changed because his speed changed. Hector's velocity changed because his speed changed. 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 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 changed because his direction changed.
To determine the answer, we need to understand the concepts of velocity, speed, and direction.
Velocity is a vector quantity that represents the rate at which an object changes its position. It includes both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity that refers to the rate at which an object covers a distance.
Now, let's analyze Hector's situation. He first heads due south at a speed of 3 m/s. Since he is moving in a straight line without changing his speed, we can say that his velocity has a magnitude (speed) of 3 m/s and a direction of due south.
Then, Hector turns west and continues at the same speed for another three blocks. Turning west implies a change in direction. Therefore, his velocity changes because direction is a component of velocity. However, there is no information given about a change in speed, so we cannot conclude that his velocity changed due to a change in speed.
In conclusion, the correct response is: Hector's velocity changed because his direction changed.
