To calculate the average velocity of a car, you need to divide the displacement (change in position) by the time taken. In this case, the car travels from a position of 0m to a position of 50m in a time span of 10 seconds.
Average velocity = Displacement / Time
Displacement = Final position - Initial position Displacement = 50m - 0m = 50m
Time = 10 seconds
Average velocity = 50m / 10s = 5 m/s
Therefore, the average velocity of the car is 5 m/s.
