Forces: A. A force is called conservative if: a. It has a magnitude of less than 0.9N b. It cannot be resolved into x & y components c. Only friction is a conservative force. d. The work done by the force between two points is independent of the shape of the path connecting the points. B. An object is dropped from the top of a 30.0 m tall building. Neglecting air resistance, use conservation of energy to calculate how fast it’s going just as it reaches the ground.
