An athlete starts at point and runs at a constant speed of 5.40 around a round track 250 in diameter

Find the component of this runner's average velocity between points A and B.

Find the component of this runner's average velocity between points A and B.

Find the component of this runner's average acceleration between points A and B.

Find the component of this runner's average acceleration between points A and B.

For a problem such as this, a figure must be provided. The answer depends upon where A and B are on the circle. The dimensions of the speed and diameter must also be provided, not just a number.
