A 5.59-kg ball hangs from the top of a vertical pole by a 2.13-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.99 m/s in a horizontal circle with the string remaining taut.
Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2.
Find the tension of the string.
