Help pl A ball at the end of a sting is being swung around a circle at a constant speed of 1 revolution per second. Why is the ball accelerating?

Since the ball is moving with a constant speed S therefore its tangential acceleration is zero direction. Now as the ball is in a circular path so it has centripetal force which is always toward the center of circular pathos the ball and perpendicular to the velocity which is along the tangent on the circle at any point. Therfore net force is always perpendicular to the velocity vector and at all points and always pointed inward.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
