#2.55 \ "J"#

We use the work equation, which states that,

#W=F*d*costheta#

#F# is the force in newtons

#d# is the distance moved in meters

#theta# is the angle of incline

Therefore, the weight is: #1 \ "kg"*9.8 \ "m/s"^2=9.8 \ "N"#.

And so, the work done is:

#W=9.8 \ "N"*1 \ "m"*cos((5pi)/12)#

#=9.8 \ "N"*0.26#

#~~2.55 \ "J"#
