Answer:

129.492 Joules

Explanation:

The work done to raise an object from the ground is equal to its gravitational potential energy, given by:

#U=mgh#

where,

#U# is the gravitational potential energy
#m# is the mass of the object
#g# is the acceleration due to gravity #=9.81 m/s^2# for the earth
and #h# is the height to which the object is raised.

Therefore, the gravitational potential energy,

#U=11*9.81*6/5#

#=129.492J#
