Neglecting friction of air, at what speed would the beam hit the ground? m = 120 kg ∆h = 96.0 m We know that gravity is a conservative force, so, energy will be conserved. We also know that while the beam is suspended there is no Kinetic Energy, and ...

Chapter 8: Conservation of Energy
... There are two basic properties of the conservative forces that are related to the work done by this force. These are: • If the work done by the force is independent of the path, the force is said to be a conservative force. Otherwise, it is nonconservative. • The work done by a conservative force in ...
