Average velocity is a measure of the displacement of an object over a specified period of time. It takes into account both the direction and magnitude of the displacement.
Average velocity is calculated by dividing the total displacement by the total time taken. In this case, it would be (1.50*10É2m - 1.00*10É2m + 5.0*10É1m) / (40 m/s) = 2.25 m/s.
The numbers represent the distance traveled in each direction (north, south, east) and the letters indicate the direction (N for north, S for south, E for east). The @ symbol indicates the starting point and the 40 m/s is the average speed of the object.
Average velocity is typically measured in meters per second (m/s) or other distance over time units such as kilometers per hour (km/h) or feet per second (ft/s).
Other factors that may impact average velocity include changes in speed or direction during the specified time period, external forces acting on the object, and the type of motion (e.g. linear, circular, etc.).
