Answer:c
Step-by-step explanation:
it is given that Adam and Boby starts from same height so their total Energy at top is
Potential Energy of Adam
Potential Energy of boby
when they fall a height h their speed at bottom will be
which will be same for both Adam and Boby
Energy at bottom
Kinetic Energy of Adam
Kinetic Energy of boby
Since velocity is same therefore kinetic Energy is same for Adam and boby
thus option c is correct
