Work#=251.1062376" "#joules

The given data:

#theta=pi/12=15^@#
mass #m=9" "#kg
distance #d=11" "#m

Let #F# be the required force to push the weight
Let #W# be the work in joules

#F=m*g*sin theta#

#F=(9)(9.8)sin 15^@#

#F=22.82783978" "#N

Compute work #W#

#W=F*d=22.82783978(11)#

#W=251.1062376" "#Joules

God bless....I hope the explanation is useful.
