A heavy ball swings on a string in a circular arc of radius 1 m. UI 19 P The two highest points of the ball's trajec- tory are Q and Q'; at these points the string is +19 from the vertical. Point P is the lowest point of the ball's trajectory where the string hangs vertically down. The acceleration of gravity is 9.8 m/s. What is the ball's speed at the point P? Ne- glect air resistance and other frictional forces. Answer in units of m/s. 020 (part 2 of 6) 10.0 points What is the magnitude of the ball's accelera- ion at the point P? Answer in units of m/s. 022 (part 4 of 6) 10.0 points What is the magnitude of the ball's accelera- tion at the point Q? Answer in units of m/s.
