an object of mass 25 kg is raised to a height of 6 m above the ground. what is the potential energy? if the object is allowed to fall find its kinetic energy when it is halfway down 

Answer» Potential energy of object when at a height of 6 m :

P.E. = m×g×h

P.E. = 25×9.8×6

P.E. = 1470 J

Kinetic Energy when the object is halfway down will be 735 Joules because the Potential Energy will be reduced to half and turned to Kinetic Energy at that time.
