Question

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

Explanation:

Velocity is a vector quantity that includes both speed and direction. The skier's statement gives distance (80 - meter track) and time (3.5 seconds), and implies a direction (down - hill to the finish line), which is related to velocity. The race - car driver's displacement is zero as they end at the starting point, so no net velocity. The basketball player's description is too vague about speed and direction, and the golf pro statement has nothing to do with velocity.

Answer:

The skier traveled downhill along the 80 - meter track to the finish line in just 3.5 seconds to win the competition.
