Answer:

Change in potential energy is 700.7 J.

Step-by-step explanation:

Given:

Mass of the object is,
m=286 kg

Height to which the object is raised above his head,
h=0.25 m

Acceleration due to gravity is,
g=9.8 m/s²

We know that for a mass
raised to a height
, the change in potential energy is given as:

$\Delta PE=mgh$ , where,
$\Delta PE\rightarrow \textrm{Change in Potential Energy}$

Now, plug in the given values and solve.

$\Delta PE=286* 9.8* 0.25=700.7\textrm{ J}$

Therefore, the change in the potential energy is 700.7 J.
