In this context:
- Speed refers to the magnitude of the rate at which the sports car is changing its position, regardless of direction. It is a scalar quantity and is usually measured in units like miles per hour (mph).
- Velocity includes both the speed and the direction of motion. It is a vector quantity. If the car is heading south, the velocity will be 6 mph south.
- Acceleration is the rate at which the velocity of an object changes with time. It can involve changes in speed, direction, or both.
In this case, the statement "a sports car goes from 0 to 6 mph in 1 second heading south" involves a change in speed and direction.
So, the answer is speed (as it mentions the change in speed), velocity (as it specifies the direction of motion), and acceleration (since there is a change in velocity over time).
