Question: A 59 g ball is fastened to one end of a string 64 cm long and the other end is held fixed at point O so that the string makes an angle of 25o with the vertical. This angle remains constant as the ball rotates in a horizontal circle. The angle would remain constant only for a particular speed of the ball in its circular path. The acceleration of gravity is 9.8 m/s2.
Part A: Find the speed. Answer in units of m/s
