a dog runs from point a to b to c in 4.00s.

find the dog's average velocity over this 4.00 second interval

find the dog's average speed over this 4.00s intervals

I can't remember the formula off hand.
Thanks for your help in advance.

To calculate the average velocity and average speed of the dog, we first need to understand the definitions.

Average velocity is a vector quantity that refers to the displacement of an object over a given time interval. It is calculated by dividing the displacement by the time interval.

Average speed, on the other hand, is a scalar quantity that refers to the total distance traveled by an object over a given time interval. It is calculated by dividing the total distance by the time interval.

In this case, if the dog runs from point A to B to C in 4.00 seconds, we need to know the displacements between these points to calculate the average velocity.

Now, since the question only provides the time interval, we don't have enough information to determine the displacements between the points. Therefore, we cannot calculate the average velocity accurately.

However, we can still calculate the average speed using the given information. The average speed is the total distance traveled divided by the time interval.

To calculate the average speed, we need to know the distances between the points A, B, and C. If you have this information, you can add up the distances between the points and divide it by the time interval (4.00 seconds).

So, if you have the distances between points A, B, and C, you can calculate the average speed by adding up the distances and dividing it by the time interval of 4.00 seconds.

Please note that in order to accurately calculate average velocity, you would need the displacements between the points, which are not provided in the question.
