Physics
A pendulum consists of a 3.0 kg stone swinging on a 4.4 m stringof negligible mass. The stone has a speed of 8.1 m/s when it passesits lowest point. (a) What is the speed when thestring is at 58 Ëš to the vertical? (b) What is thegreatest angle with the vertical that the string will reach duringthe stone's motion? (c) If the potential energy ofthe pendulum-Earth system is taken to be zero at the stone's lowestpoint, what is the total mechanical energy of the system?
