Aheavy ball swings on a string in a circular arc of radius 2 m. the two highest points of the ball’s trajectory are q and q ′ ; at these points the string is ±24◦ 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 2 . what is the ball’s speed at the point p? neglect air resistance and other frictional forces. answer in units of m/s what is the ball’s speed at the point q? 1. 0 m/s < kvq k < kvpk 2. kvqk < 0 m/s 3. kvqk = 0 m/s 4. kvqk > kvpk 5. kvqk = kvpk
