a boy is jogging around a circular track of diameter 14m. he takes 1 minute to complete the circle. find the average speed and average velocity
Average speed = total distance / total time taken
Total distance = circumference of the circle = π * diameter = π * 14
Total time taken = 1 minute
Average speed = (π * 14) / 1 = 43.98229715 m/min
Average velocity is given by displacement / total time taken
As the boy ends up in the same location after completing a circle, displacement is 0
Hence, average velocity = 0 / 1 = 0
Therefore, the average speed is approximately 43.98 m/min and the average velocity is 0.
