Solution

The correct option is A, B i.e. Kinetic energy + potential energy

Kinetic energy is the energy of motion. An object possesses kinetic energy if it is moving.

The ball rolling down a hill is in motion, hence it possesses kinetic energy.
this Kinetic energy is the combination of rotational kinetic energy and linear kinetic energy.
$T E = K E + P E$
$a t a h e i g h t i f i t i s r o l l i n g d o w n t h e h i l l,$
$a n d i f w e a s s u m e g r o u n d a s a r e f e r e n c e f r a m e t h e n, T E = K E + P E$

$w h e r e K E = \frac{I w^{2}}{2} + \frac{1}{2} m v^{2}$
