Part B

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. Part A What is the ice cube's speed at the top? Express your answer to two significant figures and include the appropriate units. Utop = 2.3 Submit Previous Answers Correct A Part B Find an algebraic expression for the ice cube's speed when it is at angle 0, where the angle is measured counterclockwise from the bottom of the circle. Your expression should give 3.0 m/s for 0 - 0 and your answer to part a for 0 = 180. Express your answer in terms of 0.
