This diagram shows the movement of a skater at 1-second intervals. What is the magnitude of the average velocity, in m/s, if the skater went for a total of 12 meters? A) 3 m/s B) 4 m/s C) 12/5 m/s D) 48 m/s
The average velocity is simply the change in displacement over the specified time interval. I’m this case, we have a total of four intervals,which represent 4 seconds. Dividing 12 m by 4s gives us 3 m/s
