Congress has often used the Commerce Clause to justify exercising legislative power over the activities of states and their citizens, leading to significant and ongoing controversy regarding the balance of power between the federal government and the states.
Instantaneous and Average Velocity. instantaneous velocity of an object at a particular time is equal to the slope of its position vs. time graph at that time. On the other hand, the average velocity between two times is equal to the slope of the line joining the two points on the position vs. time graph.
The average speed and average velocity are also related like the speed and the velocity. The average velocity is the ratio of total displacement of the object over a given time. While average velocity is related to displacement of the object, the average speed is related to the total distance traveled by the object.The equation (2) represents the average speed formula of an object moving with a varying speed.olution: For finding the Average speed of the runner, we must find the total distance covered by him and the total time taken to complete that distance. In this case the distance covered by him is equal to 800 meters and he has completed it in 80 seconds.
