Hector's velocity changed because his direction changed.
To determine whether Hector's velocity changed, we need to understand what velocity is. Velocity is a vector quantity that includes both speed and direction.
In this scenario, Hector initially headed south at a speed of 3 m/s. South is a specific direction, so his velocity had both magnitude (speed) and direction at this point.
Then, Hector turned west and continued at the same speed for another three blocks. Since he maintained the same speed, the magnitude of his velocity (3 m/s) did not change.
However, his direction did change. He went from heading due south to heading west. This means that his velocity as a vector quantity changed because direction is a component of velocity.
Therefore, the statement "Hector's velocity changed because his direction changed" is correct.
