A pendulum consists of a 3.0 kg stone swinging on a 4.4 m string of negligible mass. The stone has a speed of 8.1 m/s when it passes its lowest point. (a) What is the speed when the string is at 58 ˚ to the vertical? (b) What is the greatest angle with the vertical that the string will reach during the stone's motion? (c) If the potential energy of the pendulum-Earth system is taken to be zero at the stone's lowest point, what is the total mechanical energy of the system?
I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions
