Question

during a basketball game, a player moves forward 6 meters, backwards 3 meters, and then forward 7 meters over the span of 12 seconds. what is the average velocity? a 0.83 m/s backward b 1.33 m/s forward c 0.83 m/s forward d 1.33 m/s backward

Explanation:

Step1: Calculate displacement

Displacement \(d=(6 - 3+7)\text{ m}=10\text{ m}\) (forward is positive, backward is negative).

Step2: Calculate average velocity

Average velocity \(v=\frac{d}{t}\), where \(d = 10\text{ m}\) and \(t = 12\text{ s}\). So \(v=\frac{10}{12}\approx0.83\text{ m/s}\) (forward as displacement is positive).

Answer:

C. \(0.83\) m/s forward
