Hint: Energy in a body came due to its state of motion, if a body is moving with some speed which is body is in motion it’s called that body have some Kinetic energy and when a body remains at rest or have a restoring energy, this is called potential energy.

$K.E = \dfrac{1}{2}m{v^2}$
where, $m$ is the mass of the person and $v$ is the velocity with which he moves.
$P.E = mgh$
Where, $g$ is the acceleration due to gravity and $h$ is the height up to which a person climbs from ground level.
Note: It should be remembered that since person climbs the hill he is moving against the direction of acceleration due to gravity so the Potential energy of person will be taken as negative in mathematical formulation and the value of acceleration due to gravity is constant on earth’s surface and has a magnitude of $g = 9.8m{\sec ^{ - 2}}$.
