4. A small ball of mass m, suspended by a cord of length L, revolves in a circle of radius r= Lsine, where 0 is the angle the string makes with the vertical. (a) Determine the horizontal and vertical components of the force exerted by the cord, in what direction is the acceleration of the ball, and what causes the acceleration? (b) Calculate the speed and neriod (time required for one revolution ) of the ball in terms of L, 0,and m.
