A very slippery ice cube slides in a vertical plane around the inside of a smooth, 20 cm diameter horizontal pipe. The ice cube's speed at the bottom of the circle is 3.0 m/s.
Find an algebraic expression for the ice cube's speed when it is at angle \theta where the angle is measured counterclockwise from the bottom of the circle. Your expression should give 3.0 m/s for theta=0 and your answer to part A for theta=180.
