A 5.15 kg ball is attached to the top of a vertical pole with a 2.01 m length of massless string. The ball is struck, causing it to revolve around the pole at a speed of 4.25 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. Use =9.81 m/s2.
What is the tension of the string?
