A bicycle wheel, 65 cm across, is half buried in dirt, standing on edge. A beetle on the ground starts climbing the tim of the wheel at a rate of 1.2 cm/sec. When it reaches the top, it falls off. What was the beetle's average velocity and speed from the time it started climbing until it hit the ground?
