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 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 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.
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. On the other hand, speed is a scalar quantity that only considers the magnitude of an object's movement.
In this scenario, Hector first moved due south (in a straight line) at a speed of 3 m/s. Heading due south means he maintained a constant direction. Therefore, his velocity remained the same since the direction did not change. The speed also remained unchanged as he continued at the same speed (3 m/s) when turning west and continuing for another three blocks.
Thus, the correct answer is: Hector's velocity did not change because his direction did not change.
