when it reaches the ground all the potential energy of object converted into kinetic energy..

i work it out but i get the wrong answer i keep getting 120 joules what do i do know

souvik · Answer

when the object is at a height of 2m..its potential energy is 200 J...when it reaches the ground its potential energy converts into kinetic energy..
the kinetic energy will be 200J

i thought it was 150  but i guess your the genius here lol

anonymous · Answer

thank you so much @souvik

souvik · Answer

will you tell me why did you thought its 150 J?
