A static object at an altitude of 30 m from the surface of the ground has a potential energy of 1470 J as shown in Fig. (3). If the body falls down, neglecting the air resistance, calculate: 1) The kinetic energy of the body and its potential energy at a height 20 m from the ground surface. 2) The velocity of the body at the moment of collision with the ground. KE = ? PE = ? h- 30 m h- 20 m io Ground surface Fig. 3
