Answer» The following data was obtained for a body of mass 1 kg dropped from a height of 5 metres:



















Distance above ground Velocity
5 m 0 m/s
3.2 m 6 m/s
0 m 10 m/s

Show by calculations that the above data verifies the law of conservation of energy (Neglect air resistance). (g = 10 m/s2).
