1. Homework Statement
A heavy ball swings on a string in a circular arc of radius 2m.
The two highest points of the ball's trajectory are Q and Q'; at these points the string is +/- 27 degrees 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.
1.) What is the ball's speed at the point P? Neglect air resistance and other frictional forces.
2.) What is the magnitude of the ball's acceleration at the point P?
