Question

which statement is a scientifically accurate description of velocity? with just two seconds left on the clock, the basketball player moved quickly down the court to sink the ball in the basket. the skier traveled downhill along the 80 - meter track to the finish line in just 3.5 seconds to win the competition. after traveling at 120 kph for the entire 30 - minute race, the racecar driver ended the race at the same point she started. the golf pro missed the shot even though the ball was only one meter away from the cup.

Explanation:

Velocity is a vector quantity that includes both speed and direction. The first option only mentions moving quickly (speed - like) without direction. The second option gives distance and time (speed - related). The fourth option is about position. The third option mentions speed (120 kph) and since the driver ended at the same point she started (displacement is zero, but velocity conceptually in terms of vector nature - if we consider in a circular track etc., and the speed value is given). Also, velocity can be thought of in terms of rate of change of position (even if net displacement is zero over a race, the instantaneous or average velocity concepts involve speed and direction aspects. Here among the options, the third one is closest as it has a speed value (related to velocity magnitude) and the race context (implies motion which velocity is about).

Answer:

After traveling at 120 kph for the entire 30 - minute race, the racecar driver ended the race at the same point she started.
