A body of 2 kg thrown upwards, reaches a maximum height of 5m calculate the work done by the force of gravity during the vertical displacement

Answer»

n :-A body of 2 kg thrown upwards, reaches a maximum height of 5m calculate the work done by the FORCE of gravity during the vertical displacement ._________________________Answer :-Work done = potential energy in the height given ..Work done = m G hGiven :m = 2 kgh = 5 mg = 9.8 m/s²Work = m g h          = 2 kg × 9.8 m/s² × 5 m          = 10 kg m × 9.8 m/s²          = 98 kg m²/s²          = 98 JANSWER :The work done is 98 J_________________________________________________________________
