Aheavy ball swings on a string in a circular arc of radius 1 m. q 1 m q ′ p 24 ◦ 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 magnitude of the ball’s acceleration at the point p? answer in units of m/s 2 .
