To make billy tea correctly, the billy must be rotated in a vertical plane so that no tea spills at the top of the circular path. What is the greatest time in which one complete wirl of the billy must be completed? (take your arm as being 0.6 m long)




I got 1.55s, but the anser says 0.65s, help me out~
