Answer:
Work
⇒
W
=
98.1
J
Explanation:
It is assumed that the potential energy of objects located at
ground level is zero.
If the object is higher than the ground level, it gains potential energy
.
We can calculate the potential energy of objects above ground
level using the equation given below.
E
p
=
m
g
h
Where m:mass of object , h:height from ground level
E
p
=

98.1
J
A change in potential energy means that there is work done.
Work=change in potential energy
Work
