20. A coconut of mass \( 2 Kg \) is falling from a coconut free of height \( 10 m \). Find the potential energy, kinetic energy and total energy at the following points. \( \left( g =10 m / s ^{2}\right) \) a) Before falling from the coconut tree. b) Just before hilting the ground. c) At a height \( 4 m \) from the ground. d) Which law is evident from this example?
(a) Given m = 2 kg h = 10 m Potential energy at before falling from the coconut tree. u = mgh u = 2 x 10 x 10 u = 200 joule Kinetic energy will...
