A small ball is attached to the lower end of a 0.800-m-long string, and the other end of the string is tied to a horizontal rod. The string makes a constant angle of 67.9° with the vertical as the ball moves at a constant speed in a horizontal circle. Part A If it takes the ball 1.10 s to complete one revolution, what is the magnitude of the radial acceleration of the ball? Express your answer with the appropriate units.
