Question

A ball of mass 200 gram Falls from height of 5 metre what will be its kinetic energy when it just reaches the ground gravity 9.8 metre per second square​

Answer 1

P.E =mgh

=0.2×5×9.8=9.8Joule

Answer 2

as ball reaches the ground KE will converted to PE and

U =mgh

so, U=(200/1000)*9.8*5

U= 24.5 is ur answer

hope it will help u
